tuning issues at idle on maggied LS3 i am getting my car tuned but we are having issues with the tune at idle.
The issue is its good at idle but after warm up and running it when the car is clutched and it goes back to idle it starts over fueling the left bank of the engine by 10% or more. once the car cools it starts over and works fine til hot- any ideas?

First thing I would look at would be exhaust leaks... anytime you have good open loop fueling that goes to crap when in closed loop, it is the O2 feedback that is the culprit. Seeing false lean and adding unneeded fuel...
