I think it should be a definite option.. rather than something to think about... Get me the catch code the tune is based on from jamie.. And we'll work something out. Well as we both know, the drivability shouldn't have been effected, as the only problem with a pegged map sensor is at 22psi when its mega rich, and lacks timing, until it gets closer to the tuned boost level. My "assumption" would be that this is somewhat of the reason for the 3rd gear miss, as pilot spiro grabs 3rd gear, the load level passed through that stupid rich and mega regarded region somewhat fouling the plugs. I've had some cars particularly ZF based cars do this on gearshift, as to stop excessive wear on the ZF, I've had to manipulate the torque reduction on gearchanges, which the -10 degree's timing is enough to cause it to miss much like spiros did... I can only imagine how much worse it would be given the Fuel mixtures massively richer around the 22psi load level. The factory spark system on these cars suck arse. The only solution ive seen that works with the factory pcm is a voltage booster for the coilpacks. Which this being another option you could consider.
