    Since it doesn't happen on map0, you could borrow a Cobb from someone and see if you still get the same issue...

    ...or a JB4. I'll probably borrow Enricos stuff sometime.
    But the thing is that the car has been working perfect for 6 months without any problems or changes at all, so I'm quite sure there's something up with the hardware on the car.
    I've even tried an another Vishnu unit, without any positive results.

    I can feel your pain. My car has been working flawlessy for 6 months and now I get an occasional cylinder 6 misfire at around 3.000-3.500 rpm WOT (got it in 3rd gear, but also in 5th a couple weeks ago).

    I need to check if it also happens on Procede map 0. If it doesn't, I'll switch to COBB before I replace the injector.

    Does anyone have the latest injector part number btw?

    My high rpm misfire occurs every time both with and without meth. The only time I don't misfire is on map 0.

    The only thing I know is that it does misfire on map 1 and 2 (14 and 18.5 psi) and that it doesn't misfire on map 0 (7 psi).

    mine did not missfire on jb map 1 and 2 or 0 . there was a boost threshold that made it missfire. on map 5 and map 3 add45 missfired everytime so your lpfp socket filter clogging theory might be true.

    Get the GT-R, and then maybe will get a NissanBoost.com from @Sticky (and of course a change from Germanboost to Worldboost).

    Seriously though, I kind of miss the N54 (even with all issues it has)...

    Turning misfire detection off is not very smart.

    I agree not smart, but that's the only known way to fix it.

    I seriously feel bad for all these cars with phantom misfirings. I would seriously de-mod the car and sell it if I had that problem.

    Oddly, the issue seems to crop up from long-time Procede users more so than others. CPS related? Coincidence? There seems to be a strong correlation.

    The piggy backs definitely can cause these kind of misfires. I was hunting down a JB4 one the other day. Basically the tune wasn't remembering what it learned and that triggered misfires when the fuel mix was different than what it remembered. I was on alpha software though...

    Sorry, I should of said I was getting misfires on autotuning maps even with the same or very similar mixes of E85. Pretty interesting.

    I guess I get attached to cars, I even liked the Prius I had (very short moments though)...the 997tt is at the dealer since its still leaking coolant. And a FBO+meth n54 is so much more fun than a 1.6TDI Golf DSG. BTW that rental would be 100x better with a normal automatic, in slow traffic it is horrible. Only reason it got a dual clutch was to save fuel.
