So my buddy has an 05 with an e1. He is on stock injectors, pump, wga, and he's got a 3" exhaust. Since there is no stage 1 for 05, I took a stage 2 program and put all the stock values into it. Once I did that the car would boost way to high in any gear with the exception of first gear. Btw, he is on the 2.25 bar sensors which is why I did what I did. Since it boosted really high, I took 15% out of the bottom three rows on the desired torque table and now it boosts about 16 psi. Now that the boost is ok it popped up with a P0123 check engine light which is "throttle/pedal postion sensor/switch A circuit high input."
Now that the boost is ok it popped up with a P0123 check engine light which is "throttle/pedal postion sensor/switch A circuit high input."
I dunno what to do now.
I know,,,,Fix it.
The code for high TPS voltage(>4.4721v) doesn't happen on its own. Something has failed(wiring or sensor). Follow the Factory diagnostic procedures and fix it.

Thank you. I wasn't sure if that was because of what I did in the tuning or because he just happened to get a faulty TPS. I will check the voltage at the tps next time I am with him. Would it be ok to do that through the OBD II port? Or do you suggest manually doing it?
since you seem to have the stock WG
why don`t you keep the stock 05 code
and remove over boost code
you should be good with that
not totally sure...was running clamp and tip mod when i was still using the code
if you change the wg you will probably end up with a correlation error
and by experience you get into limp mod if you stay above 6 psi for about 1 or 2 sec when in ptb but with stock wg you can`t go that hi

Because when I did that, I had problems with the rear O2 sensor still wanting to throw a code... Some of the stuff that is supposed to be turned off with certain values didn't always seem to work... I dunno why, but that's what happened... I might try what you suggest also, but he said everything is fine now. No more CEL... So I dunno...
