Limp mode - safe mode

I know the LS2's do have a "safe mode" with their electronic throttle - and that there had been an issue with the throttle in LS2-powered GTO's going into "safe mode" - which was traced back to the accelerator pedal itself.

Other than that, there may have been something else in the system - including the fact that GM has some tune-limits programmed in for the first 5000 miles (many LS2 cars seemed stronger after this "break-in" period)
