I got the ECU back around 10:30 Friday morning, installed it and have been really happy since! There is a considerable power gain in the lower RPM range and a bit more throughout. Throttle response is way better and the rev hang is gone. I'vs gone 90 or so miles so far and will update when I fill up. Overall a Greta tune from a great company! Thanks Danny and the rest of the C2 guys!
