car is am 08 427 TT C6 Z06 with an HPT 2.5bar SD tune.
the car would only go up to 7.5psi without misfiring, anything above that and it misfires crazy.
The last time it did this I was sure I had (not so good) wires which were a little burnt from the manifold, but this time I have new coils, wires, plugs everything. FYI #7 plugs gapped at 0.30, I dont know if its time to close the gap a little more though.
Still didnt put the car on the dyno to verify, but on the road it seems to misfire at the same boost level, my local dyno tuner ran out of ideas himself and said its not in the tune.
ill post up a log where in every instance above 105Kpa Map I let go only after it mis-fires, just so you know when its misfiring.
Im also thinking MAYBE the pass. side turbo inlet MIGHT be collapsing under boost, but I did not verify that yet.
Can anyone take a look at this log, and see if you can come up with something?
ambient temps were: 35degrees C.
PS. sorry, I hope this doesnt sound weird, but I dont think my tuner would like me to post up "his" tune on public, unless someone can offer direct help, thanks for understanding.
