I just got my car back from body shop and I floor it from a stop and it upshifts, does not spin wheels and no power off the line. What could be the problem? They replaced all radiators, oil cooler, heat exch, ac condenser, rad fan. Tranny fluid level ok. All vacuum hoses look ok. This has kleemann ecu/tcu so it normally lights up tires even with esp on.????????

Check the transmission mode...if it is in W mode it is starting in second gear.

happens in all modes, even worse in c mode which used to be w mode. turbos are not making enough boost in 4000 and lower rpm.

Had dealer run codes and diagnose, boost and tranny codes came up: P2001 Charge pressure too low and P2318 One or more messages from control unit N15/5 (Electronic selector lever module control unit) are not available on the CAN bus. (CAN timeout fault) ---both current and stored. Anyone know what I need to do?

Maybee the body shop did not bleed you intercooler system properly. That could make your car feel like a dog.
