When I first got mine I felt like the engine was a bit constipated, especially when trying to accelerate up a freeway on-ramp. I now realize that was the "break in" mode of the ECU which limited the RPMS. I had also added the G56 air cover and thought that is why things changed. I now think it was probably after the break in period of the ECU
