    AD intercooler showed up this morning. Thing is seriously bad ass. Looking forward to getting it on the car. Hopefully have it up and running this week. While everyone else continues to discuss magic numbers, and HPFP's. We continue pushing things forward in the background as we always do. Enjoy the pictures.

    I've been building custom maps for MHD since it was in early Beta in January and have had some success, I have about 50-100 people running a variant of my maps either standalone or Stacked. I made a separate email since there's been a ton of demand for custom tunes, I'm not charging anything, obviously donations are fine as this has taken a lot of work, trial and error, trips to Mexico for 120mph+ logging etc.... I really just want these out there and hope you all take these base files and run with them! I know a lot of people build custom maps and I wish people were more willing to share. Here's my attempt. I currently have: IJEOS E60 IJEOS E3O IJEOS Pump+Meth IJEOS Pump Beta I8AOS E60 I8AOS E30 I8AOS Pump + Meth Email me at spxtuning@gmail and I'll get the correct map sent over!

    Hey guys, Like many of you, I am running the 3.46 final drive ratio from the AT in my 6MT car. I hadn't noticed any issues until logging the other day, I noticed the "gear" monitor always shows 5th gear as if I'm in 4th. So, since "gear" is calculated, I went off on the search for the gear ratio calc table and defined it. Two questions: a.) I'm not sure about the math on this one. I know it's not as simple as copying the AT's values, as the gear ratios are different. Someone care to help? b.) Will running different tire sizes effect this? Here is the table, for reference. x-axis units are h/(km*min)

    ORDER LINK Finally, an affordable intake system worthy of your S55 M3/M4! The BMS S55 Performance Intake retains everything that is good about the OEM intake including the cold air ducting and light weight heat shielding airbox bottom, but replaces the top end of the intake with higher flow ducting and quality inverted cone air filters to match. During our dyno testing the BMS S55 Performance Intake performed the same or better than other S55 intakes tested posting gains of up to 10+ horsepower to the wheels at 25psi+ boost levels. Note the OEM S55 air intake flows very well from the factory so gains are mostly present at higher boost levels and higher RPM where airflow requirements are highest. In addition to freeing up some power turbo spool speed was improved, and there is an incredible sound improvement. You'll finally be able to hear your turbo spooling! Installation is easy and fully reversible. Our proprietary high flow filters can be cleaned every 15-20k miles using a S&B cleaning kit and will last the life of the car. Our intake temperature testing found no significant difference from the factory intake during both sustained cruise and full throttle operation. BMS S55 //M Performance Intake • Adds up to 10+ Horsepower • Dramatic sound improvement • Super fast install and removal • Improves throttle response • Retains OEM airbox base as a heat shield • Retains OEM cold air ducting • Looks great under the hood • Cleanable and reusable filter • Made in the USA Applications: BMW M3/M4 • 2015+ F8X M3/M4

    Hey I'm experimenting with a new tune setup and want to see if I can modify the torque limiter as opposed to just deleting it. Currently I can't get the limiter higher then 510nm.. I changed most limits and I thought maybe it had to with torque limit offset A because that's set to 510 NM but no go. It's possible I'm being dumb and missed something. Anyone had success?

    Hello everyone, I'm sure this has been discussed a lot in the past but can't find a sure answer. My car is a 09 135i AT with 86k miles and after installing VRSF catless DP's and berk full race exhaust my car smokes a lot and smells like burning oil while slowing down and coming to a stop. I did also notice the oil is being consumed quite faster than before. Took it to a local knowledgable BMW shop in my area and they checked the turbos and they looked fine. They are saying that the issue might be from the valve cover because its leaking and that the whole thing needs to be replaced, and noticed that the oil filter housing is leaking as well. They also recommended that I have the intake manifold valves walnut blasted. Do you think doing all the above will stop the white smoke on decel. and when coming to a stop? and would upgrading to a RB PCV valve help resolve this issue? Thanks ahead!

    I've got a kid in college now so my mod budget is limited... I'm wondering what's the best bang for the buck mod upgrade for an FBO N54 to get to 500 whp/500wtq? From what I've been reading on the forums, the latest developments in inlets and Fuel-It's throttle body injectors (TBI) look to be very cost effective for substantially bumping up power for an "almost FBO" car like mine. I am currently running an E40-E50 flash only Cobb ATR tune on my "almost FBO" (sans kitty less dp) 335xi AT which Virtual Dyno says I'm achieving 400 whp/460wtq at 18 psi max boost. Do you think I can reach 500/500 with just inlets and/or TBI on E85? If so, would I need to increase my boost to over 18 psi, and could I do that flash-only, i.e., which tables in ATR should I adjust? Would I also need an N20 TMAP sensor to do this correctly? Thanks for your input.

    As you likely know the 2015 BMW X5M and X6M are second generation models. Although they still have a 4.4 liter twin turbo V8 and automatic transmission the vehicles were updated to the S63TU 4.4 liter V8 that features the Valvetronic system and they also feature new BMW programming. This necessitates new software for aftermarket tuning and Velos has such aftermarket software for the new M SUV's. The X5M and X6M in stock form are rated by BMW at 567 horsepower and 553 lb-ft of torque. On the Dynojet this translates to 493 wheel horsepower and 499 lb-ft of torque at the wheels. This is less wheel horsepower but more torque than an F10 M5 S63TU. BimmerBoost hates to toot its own horn but sometimes we have to remind people just how good a of a job we do: 'If BimmerBoost were to speculate BMW likely upped the boost a bit with the addition of Valvetronic and tuned the motor for more of a low end torque profile than the F10 M5' That speculation from last year proved accurate. The X5M and X6M are not revving out past 7k rpm and are tuned for more torque down low as these SUV's are expected to actually tow. With the addition of a Stage I pump gas tune peak horsepower goes up to 544 to the wheels and peak torque to 577 lb-ft at the wheels. Gains of 63 horsepower and 78 lb-ft of torque respectively. The X5M and X6M obviously suffer higher drivetrain losses than the F10 M5 or F13 M6 with the automatic transmission and all wheel drive. Tuners will not hit the same peak numbers with the S63TU equipped SUV's as they do with their rear wheel drive DCT M6 coupe and M5 sedan counterparts. It will be interesting to see who gets the X5M and X6M over 600 wheel horsepower first.

    Hey guys, I just removed the OEM inlet pipes and wanted to share my experience with the community to maybe help someone else out. First of all, I did this during a turbo swap so the subframe was out which was helpful, so if you are planning to go with upgraded twins I highly recommend doing this job at the same time regardless of whose Inlets you decide to purchase. The rear inlet is simply going to have to be cut. I tried about 10 different ways to remove it in one piece before finally submitting to the fact that the only way to accomplish that would be to drop the motor, simply too tight near the rear turbo area. I will upload some pictures tomorrow to help with the visuals. But for now I will add the text while it's fresh in my mind. This write up assumes you have read other write-ups about getting everything cleared to the point of removal such as down pipes, filters, fresh air cabin filter deck, valve cover beauty cover, drained coolant system and removed the reservoir tank and vacuum canisters. If you are doing turbos at the same time you'll also have the old units removed and water pump and Thermostat. Plenty of write-ups for all of those with a quick search. For the rear inlet, make sure you remove the pcv hose amd small wire plug going to it from the inlet. Therw are two tabs on the front and back that must be gently pryed out with a small flat blade screw driver. It then simply pops up and out. There are 2 T30 torx screws that hold the inlet to the back of the cylinder head. There is no room to fit a ratchet and socket back there so it took some Macgyvering to accomplish removal. I used a T30 bit from a cheap screwdriver bitset I have had for years. These can be found at almost any hardware store and usually come in a case or rubber strip with various other type bits and screwdriver heads. It requires a 1/4" wrench, I have a full set of ratcheting wrenches which made the job much simpler. I put a layer of electrical tape over the back of the bit to hold it in the wrenches boxed end and keep it from sliding around. It takes a minute to situate your hands over the passenger side fender and get back there and feel the torx bit's way into the screw head. Once you get it in, break it loose and give it about two turns to fully losen it. For mine after that they were easily removed with fingers to expedite the task. Both are accomplished the same way. With wverything disconnected from thw rwar inlet and it being loose now, you can get at it from under the car and pull it off the turbo (if your not swapping to hybrids and already have them removed) and pull it towards the passenger side of the car as nuvh as possible. I cut the thin tube with a small body air saw which made quick work through the plastic. But you will likely need a longer sawsall blade if the turbos are not being removed. You should cut it just before the bend towards the turbo inlet. Once it is cut it will pull out easily from the top towards the drivers side of the car. Rear one done! For the front inlet, I think it will need to be cut to remove unless your turbos and estriol are your for replacement. Mine were out so I was able to remove the two t30 torx screws holding the inlet to the front of the motor . I was able to use a ratchet on these, tight but workable. Once loose, fingers again were faster and easier then continuing with the ratchet. I then removed the large upper radiator hose, quick spring clips just like throttle body flange, simply use a small flat tip to lift it up and snap it into the unlocked position. These hose fitting were tight and required some wiggling and light pressure with a large flat blade driver to break loose. Don't get crazy when prying, it is plastic after all. Once both ends are loose, remove and see the new clearance available to maneuver the inlet. Mine went out the bottom with a little twisting and care to make sure all the hoses were unlatched from the molded on loom on the inlet. Much cleaner looking with it removed and belt changes look like they will be a snap now. If your turbos and waterpump are still on the car, you will need to cut the inlet same as the rear one and remove from the top. All in all the actual job of removing the inlet with the right tools I listed isn't too bad but requires removal of alot of other items to gain access. I would say after doing this that I would wait and do Inlets at the same time as upgraded turbos or at least downpipes because the job piggy backs well and will save alot of extra work. If you are just doing inlets and want to remove all of the oem inlet piping, Plan on about 4-5 hours start to finish first time around with proper tools on the fast side and more if your a leisurely wrenches. Hope this helps and I will post up some pictures tomorrow to go along with the writup and make things clearer! Chris

    I suppose many N54 users have turbo seals going bad, turbo siren etc.... I don't want to go to stage 2 turbos because I love the low end response of stock turbos, but would like to have an upgraded CHRA with improved seals etc.... For the install, to avoid a LOT of work, I would change only the CHRA, keeping the original manifold and compressor vane. Could a vendor VVT, pure, RB etc propose an improved CHRA, with original (or imroved but fitting original manifold and vane) wheels? I really think there is a market for this!

    Trying to get a McLaren P1 versus Ferrari LaFerrari comparison without Ferrari politics spoiling the show is virtually impossible. Really, we would just like to see a race between the two just for fun as we all know the cars are incredibly capable around the track and it really comes down to the driver and tires as to which one will win. Magazine times show the cars are very close with the LaFerrari times and the P1 times from the same sources essentially telling us they are neck and neck. The thing is, they are not testing the cars at the same time at the same location. Ferrari is forcing magazines to do their testing under Ferrari's watchful eye in Maranello. Let's look at the acceleration figures from both cars from Motor Trend: 0-100: McLaren P1 4.7 seconds Ferrari LaFerrari 4.8 seconds 0-150: McLaren P1 9.9 seconds Ferrari LaFerrari 10.0 seconds 1/4 mile: Mclaren P1 9.8 @ 148.9 Ferrari LaFerrari 9.7 @ 148.5 Piecing together magazine times tested in different conditions at different locations on different days is a pain in the rear to say the least when trying to get an accurate picture. This video may not be the best as there is no in car view and it may not have any recorded times to go with it but it does show the two cars running each other from a dead stop twice. Each time the P1 edges the LaFerrari out. This is the closest we are going to get to a direct run between the two for now without Ferrari's blessing:

    So fairly straight forward question: Can I tune my car using the BimmerBoost flash with a BT Cable without needing to buy and install JB4. I would assume the answer would be yes as this was the open source solution developed with Sticky helping pull a team together to build it. But, I'm confused though as most posts talking about it over on N54Tech about it seem to mention having JB4. Alternatively, if that doesn't work I'd look at Cobb. ------------------------- 2008 BMW 335i 6MT Convertible
