Well, I just got my car back with new turbos installed (under warranty) and new vacuum solenoids. Expecting it to feel like new, I was happy to get on the highway....but something feels off. Like I am not making full boost consistently. No way to log, car is stock for now. One weird observance- in third gear, WOT, the rpms would climb non-linerally ( fast-slow-fast-slow-fast-slow), but this phenomenom ceased after driving for a while. Yet, no CEL's or SES's So:

1) Is this just getting used to a stock car?
2) Is there some sort of break-in for the turbos before they will operate fully?
3) Could this be a boost leak somewhere, or what else could it be?
