Acquired an SRT4 that runs pig rich in boost and the tune just seems off. Pulled it out and did a datalog, if someone could take a peak at it and help me get it lined out a little better so its at least drivable without washing cylinders.
03 SRT4
Stage 1 PCM
AEM intake
2.5" turbo back
AGP wastegate actuator
RC750cc injectors
BFMIC with SSQV
3bar map/tip
for some reason i can't up load the tune.. (pm if you have any questions )
for a base static pressure of 58psi (stock) multiply the factory fuel by x1.5, and for the startup base multiply factory by x.66

Not much wrong with the tune but even though you barely logged anything useful, the car shows issues.Originally Posted by Sxtrider
TPS isn't registering WOT most all the time, so the A/F should be VERY Lean, not rich. So that brings into question the accuracy of the Wideband.
