    How does providing an example here prove your point?

    Answer was no as I disagree its a solution. Its a workaround. In my world those two are very different.
    You were inferring rbs are not reliable when fully maxed out; I am not disagreeing with that but we are comparing all-out glory runs, not what you constitute as reliable. Technically stock is the most reliable you can get.

    I think the misfires have different causes each time. I watched Shiv bypass CPS on a car at the runway and I don't think it resolved it. I had the same problem too for awhile. IIRC always cylinder 6 at higher boost levels. After some work I found my dealership, who also replaced hotrods injectors, failed to install the isolating ring on that injector. Never a misfire since @ 20psi. But if you've thoroughly eliminated every possible cause then you might as well try disabling misfire detection. It's a great tool available to us now thanks to Cobb.

    All the cars seem to have the Vishnu flash in common which is mapped out at only 2-3psi per their notes. It's possible the flash itself is the cause.

    So your solution was a workaround?

    My point is you can only provide one example of a user other than hotrod exhibiting this phantom misfire issue.

    His issue could have been fouled o2 sensors or all that nitrous coming back to bite him in the ass.

    Not saying you are wrong, but I don't think anyone on Cobb is making the same power as we are discussing, which could be an element to the isse. The issue doesn't happen when I lower boost.

    Not sure what your point is right now Click here to enlarge I'm not inferring anything. I'm trying to set realistic expectations out there given what the OP said in reference to an RB number being 550 and comparing it to a 580whp ST number. That's all.

    Simple, you are preaching reliability in a discussion that does not warrant it; 500 whp or 550 whp alike.

    Although I have my share of issues with both shiv and the procede, I am just saying this issue seems more commonplace on this tune than any other.

    Yes, I am having some issues with misfires at ~6500rpm, very similar to the same issue that DZENNO had (who never had a Vishnu Single). We are still working on a solution. This forces me to shift aroun 6300 or I'm guaranteed to go limp.

    At PBIR, I only managed to get one clean run, which was my first run. I was shifting at 6200-6200 (900-1000rpm short of redline). I did 12.50 at 121.6mph.

    The Friday night before at OSW I did 12.7 at 123mph.

    All these passes were at 23psi. Once everything looks good and is running right, I will go up to 25psi (which is where I would make close to the claimed 650whp). At 23 psi and at 6300rpm, it's probably making 510-520whp.

    From my experience drag racing, I'd be willing to bet a good some of money that the car will trap over 130mph when I can shift at 7200rpm at 25psi.

    Other issues I'm having is my ACT clutch is dragging. I couldn't stay still at the line and hold rpm without rolling past the beams. This also means I couldn't use 2-step to launch. Try launching a big turbo car without building boost. It is no fun and is laggy as hell, so I'm essentially wasting distance.

    I also couldn't use NLS because of the ACT clutch. It doesn't work well because of the low engagement point. ACT clutch is coming out this week for a new Spec clutch.
    Repped for posting despite the car not being 100% She'll be a beast for sure once everything is ironed out!

    I doubt his flash is the cause for reasons I outlined above. These issues are ALL very similar if not the same. Namely:

    1) Misfires in bank 2
    2) Fuel injection cut off
    3) Happens past 6k rpm always
    4) Doesn't happen in gears 1 and 2 ever, only 3rd and up

    It "could" be anything but its awefully similar to all others having the same symptoms.

    +1 for putting it on a dyno and turning off misfire detection to see if it's actually misfiring, I never would do it to clear up my 4th to 5th shift misfires that hotrod and I shared but that was on nitrous Click here to enlarge

    A workaround is only a solution to a manager type, lol

    And why the heck is he doing that again when he's tried the same thing up here in Canada 2 years ago and it didn't do anything?

    This thread is blowing up! All of this hush hush hasn't gotten these issues resolved any quicker. We are seeing what happens when this is brought to light and some of the more knowledgeable people in regards to this platform chime in. An open discussion very well could help move this along although I'm not sure how willing people are to help Shiv.

    Screw Shiv, but outside of Sikh335 I don't have anything against the guys that bought into the ST, the more the community can help them overcome Shiv's premature ST release and get a working setup the better.

    Remember misfire detection "rough running" is mapped on various parameters including load, rpm, etc. I always suspected the reason Shiv mapped everything out to 2psi was to dampen the misfire detection tables. Although, such a change might also have other side effects. Even something as seemingly innocuous as running your coil power through a relay system could contribute or cause it.

    This is new to me, what is the max PSI that you can dial in before the misfire starts ?

    But it did. Remember, they had a CPS programming error and board design error and "fixed" the problem with Rev 2.5? Maybe he suspected the CPS was interfering with the flash. It's the first thing I would have bypassed as well in his shoes.

    I think everyone is a little confused by your neutralism when it comes to this topic. It's pretty obvious in this situation that right now, it seems like a Procede specific issue. Yes other cars have had mysterious misfires running different tunes, but those people never fully ruled all potential hardware issues.

    Your neutralism almost looks like you're defending Shiv and his tune, which is downright offensive and blasphemous.

    How dare you.

    I'm talking about troubleshooting persistent high gear high RPM misfires on 6MTs. Bypassing it entirely didn't help anything on my car.

    Interesting theory...I'll chew on that one for a little bit.
