I think we're going to need more than just a tune as I had Jerry retune my ECU for high boost when I first installed the combo. I believe the MAP and/or fuel system needs to be upgraded as well. I think the first place to start would be a 3 bar MAP sensor w/ retune. It will still work with the 0-5V signal, but ECU recalibration will be absolutely necessary. The stock MAP just cannot read high enough, and the ECU doesn't know what to do when MAP output voltage approaches 5V anyway. A 3 bar MAP won't reach 5V until about 29 psi which puts 23 or 24lbs well within the ECU's range. (Just my .02)
Please keep us posted on your results! I have gone back to running just the ASP pulley for now with great results on the C32 (a few hundred pounds heavier than the SRT6).
