Fault codes lower power
 

I used torque to scan the ecu for fault codes and got these back

P1516: [Chrysler] Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance

P1517: [Chrysler] Electronic Throttle Module

P1518: [Chrysler] Electronic Throttle Module to PCM Communication

I read it has to do with traction control is it true?

Driving with traction control off i can feel more power and driveability... Otherwise power feels crap

Oh and its a 2000 c5, 6spd

Ok the TQ management system uses both the ABS brake system and the traction control system to reduce TQ when the ECM deems there is a fault or an over torque in the engine
at shift points or at certain TQ max levels
Typically these are all false triggers of the TQ management system--Any tuner can delete all these false TQ deducts from your stock tune by deleting your TQ management in your tune More so on an engine that has been modded so the HP and TQ is more than the expected stock numbers----- I would reccomend a tune this will delete all the stock TQ mangagement in your tune plus will allow your engine to make all the HP it can all the time at any RPM without the ECM trying to limit the TQ as the stock tune dictates
