Need s3 SRT4 help x430
Other than you driving the car its hard put into words what its doing but here goes studders on half to WOT the higher the dab the worse it gets WOT no accel no power just noise lol (cries). Vac lines, spark plug wires, plugs an gap good, one bad o2 but thats not the reason trust me its the last one. Mods full stage 3 w/toys port n polished head, ti springs/ retainers bc s3 cams/ fidanza cam gears, oversized valves 1mm. should i just go after market bov/ wastegate? plugs are at .040 not going lower they feel right could it be the nah dont think its the clutch? Cam gears is another Question....many a diff settings blow 0/0, 1/1, ex -2/in +2/+3 sucks bad well....bad thats the setting right now cause im gonna need new screws. Yes everything else is all mopar stage3 fuel pump, maps, pcm etc.

Sounds like a sensor calibration problem, or a bad MAF/MAP sensor. The PCM just does what it's told, so if you give it bad sensor data, it will give you bad control outputs accordingly. Have you checked the TPS calibration and that the manifold pressure is in the right range at idle?
Did it just start doing this or has it always done that since the stage3 upgrade or the last time you modified something?

The TPS sensor wires are shit.Dodge screwed up when they routed the wires and didnt make them long enough,mine acted a couple of different ways when the TPS wires would get loose/break. It also took a while for a CEL light to come on.It appears to be a sensor problem like Fabrik said.

eh....my tps wires acted funny too, but not quite like that. dodge replaced mine, the car liked to give itself throttle, and the throttle would sometimes stick, and sometimes the car wouldnt run, but not anything like what youre describing.

Still sounds like a sensor problem. Your turbo being that hot will be from one of two things usually:
Either the A/F ratio is not right, so your EGT is too high, or the ignition timing is too retarded, making a mild version of anti-lag because the combustion is happening so close to the exhaust valve opening.
