    Noticed this today and unsure if this is a sign of bad vcg or should I look elsewhere to see where the oil came from..?? It's right next to coil #2 in that little indented circular part.. Thanks!

    Champion Motorsport is readying their 991 Turbo and 991 Turbo S intercoolers for release. PorscheBoost member @sdg1871 is purchasing these intercoolers to along with a revised GIAC ECU tune for the 991 Turbo and S platform. This member has combatted heat soak issues and GIAC themselves finally commented that the 991 Turbo platform indeed suffers from heat soak. Further details from @sdg1871 below. Two days ago, I visited Champion Motorsports to discuss the work that I want them to do on my car (install the upgraded intercoolers/Y pipe, datalogging with the new mods to ensure they are functioning properly and eliminating my car's heat soak issue and possibly changing to catless exhaust). As usual, Tom was terrific and informative. And finally some good news for those of us waiting so long for their intercoolers for the 991 TT and TTS -- they will hit the market very very shortly (as in days not weeks). They have enough finished product for an initial run of about 14 sets. Shortly they will write their instruction manual for installers and the kits will be released. These will not be cheap as they included huge upgraded ICs, a Y pipe and what looks like very upscale carbon tubing. Here are my photos of the new IC kit parts and comparison photos of their new ICs vs the stock ICs. The Champion ICs (on the left in the pics) are a lot wider than the stock ones (on the right in the pics) and have more rows in their core -- meaning that there is a much larger surface area for heat exchange than the stock ICs. The GIAC tune that is paired with the new ICs (I have no idea what GIAC is calling it but I would call it Stage 3) is supposed to be a lot more aggressive than the Stage 2 tune. I am told there is a significant power bump in absolute bhp and torque and that there will be a lot more power at higher RPMs (as I understand it, due to the enhanced intercooling they can push the turbos harder at higher RPMs than with stock cooling). I know what the numbers are but I certainly wouldn't scoop Champion and GIAC in putting them out. What I can say is that they are excellent and don't rely on water/meth injection, nitrous, sensor/cat-destroying leaded race gas or other techniques to get there (although I am sure with those other techniques the power would be greater still). Can't wait until cars with these new IC/Y-pipe kits starting hitting the dragstrip so we can see the performance difference in the real world. I certainly hope and expect that the real world numbers will mirror the big gains being seen on the dyno. Maybe we will even see nines in the quarter mile in the fall when the air is cool. They are also actively testing and datalogging a turbo upgrade. That looks to be at least a few months away from market. When I was there their test car was on the dyno for data logging for the turbo upgrade (it had both the ICs/Y pipe and the bigger turbos installed). Should be an exciting development for those looking for the really big power.

    MFactory started a thread Electronic Exhaust Bypass in N54
    Hey guys, just putting up an interest/feeler thread to see if this is something that you guys would be interested in. TBH, I've not done enough research into this area to be certain or not whether this would be a popular modification on the BMW, but from what I've seen so far, it seems that a lot of you do actual physical modifications (i.e cut/weld) to achieve the exhaust bypass? being VERY popular in the Ferrari world (which is where my experience with it comes from after installing on my 458), it is basically an electronic controller that piggybacks onto the stock solenoid valve, allowing you to remotely activate/deactivate the exhaust valve either via a wireless controller (included in the kit), or by hardwiring a switch. the system is 100% plug and play and requires no physical modifications, therefore is 100% reversible in case of stealership warranty/servicing. In the case of the BMW's, takes less than 1hr to DIY. the kit is very well tried & tested (as I mentioned, we have been using them on Ferraris for years now) and retails for under $400 shipped. again, this is just an interest/feeler thread. If you guys are interested, I can provide more details. If not, no harm done :) Thanks!

    Hey fellas, It seems my hpfp is struggling to keep up at the moment with my rbs on 23psi e50. Even with 50% meth (cm10). It drops to around 10 during most of my logs, seen 9 once or twice. I know it's been replaced before by the previous owner, but is there a way to get bmw to get me a new one? Or does our hpfp not wear out like a regular fuel pump, but instead is either good or bad, no in between? Thanks!

    Are you tired of the politics? Tired management that shouldn't even be telling you what to do? Tired of the same tech getting fed, and you having to do the same low paying work? ABR is looking to hire another super star. We have a TON of work, and want a TOP FLIGHT BMW tech that can walk the walk, and talk the talk. ABR has numerous mentions in the aftermarket and independent world. We're the only company in the world that strokes the N54 engine, and have the most custom internal parts available for them. We pride ourselves in knowing that we perform top tier work, at a fair price. Most importantly, we want EVERY client to feel comfortable with our service. If you think you have what it takes to be the next level technician, send me a resume to and let's talk!

    I was running jb4 map without any major problems, except my ff would learn all the way up to 150. I gave mhd a shot, to lend my buddy my jb4, and it boosts under target after 5000rpm. are these 2 issues related? if so what could it be? I'm gonna rip off the dp's and adjust the wastegates asap. What else could it be? 335xi mt dp's 5" stepped fmic bms dci brand new plugs on mhd logs mix of 99 unleaded mhd to rule out timing mhd logs jb4 logs

    The controller doesn't affect your cats, so shouldn't cause any CELs. It directly controls the solenoid valve in the exhaust. I completely understand that a lot of people just simply change their exhaust/testpipe so that it eliminates the valve completely, or do the golf-tee mod to keep the valve permanently open (this is also popular with the Ferrari guys), so this mod is mainly for those who wish to retain their stock control valve for quietness and/or warranty purposes, yet have the ability to run "open" whenever they wish. As for pricing, depending on the interest, I'm sure I can work out a different pricing structure with the manufacturer.: Exhaust Bypass Valve Controller Kit is a complete solution that allows the user full manual control of the vehicle's vacuum actuated exhaust bypass valves. The controller has an integrated printed circuit board that controls the negative side of the exhaust bypass vacuum solenoids. The user can manually open the exhaust bypass valves to have that classic engine sound at all speeds and engine RPMs. Of course, you can return the operation of the exhaust valves to the car's ECU — which generally results in lower engine noise at low vehicle speeds and engine RPM. The Exhaust Bypass Valve provides three different operational modes: 1) Normal Mode: In this mode, the vehicle controls the operation of the exhaust bypass valves. This is the stock operation. 2) Always Open: Selecting this mode will force the exhaust bypass valves to the open position — and remain open. When the valves are Always Open, you have the full experience of hearing your engine exhaust at any time. 3) Always Closed: Selecting the Always Closed mode will force the exhaust bypass valves to remain closed at all times. This overrides the ECU control which opens the valves at predetermined engine and vehicle speeds. This mode is especially useful to ensure that your vehicle is as quiet as possible. Note: With this option, you can force the valves to stay in the closed position at all times. This feature was added at the request of people who track their cars at locations with strict noise standards and did not want the vehicle ECU to open the valves at high engine RPM

    PLF replied to a thread Electronic Exhaust Bypass in N54
    Interested but at a lower price point, let me explain by stating my situation. I would like to use the 2-step/rev limiter as I would like to at the strip but I can't because I still have the secondary cats and these fool my AFR if I keep it for too long on the 2-step and makes the car go on limp mode... But.. I love having my secondary cats because they cut fumes and smell and noise... I did a custom cutout install on my DSM a few years ago and loved it but having a Bolt on on my 135i that would bypass the cats would be awesome !! At 400 bucks I could just buy a N55 midpipe and be done with it..

    The factory exhaust is pretty quiet even with the valve open, I think most people just force it open all the time ala the golf tee mod. Aftermarket exhausts typically delete the valve all together making a controller moot.

    You're in the fortunate position of being insulated by ACM. I wish I had the same deal. The bottom line is, you can't count on Gintani. If I could my car wouldn't be there for six year and counting now, right? You're stuck somewhat and so am I but I think ACM will have your back which is nice. Gintani has no idea how to quell the haters and speculators. They simple don't have that extra edge of professionalism or self-awareness and we all know it. If they did, they would have finished my car and utilized the incredible resource they had which is an administrator of a BMW forum pushing a platform and being their customer. Hell, I fought most of their battles for them. Underwhelming doesn't even begin to cover the experience. Once again, good luck. I've reached my fill with Gintani. Six years is enough.
