There isn't much difference comparing these two tunes on paper so I'd like to hear opinions from those who have had both or have driven cars with either tune. Looking at 91 octane tunes BTW.
APR is more convenient as they have dealer about 10 minutes away compared to C2 where I'd have to drive about 6 hours round trip or mail the ECU.
I don't plan to have more than a short shifter, tune and an intake. Ever. I'm looking for bad experiences like worse mileage, inaccurate claims and poor tuning like black smoke or just running like crap.
My thoughts after the tune: I got the ECU back around 10:30 Friday morning, installed it and have been really happy since! The tune provides 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've gone 90 or so miles so far and will update when I fill up. Overall a Great tune from a great company! Thanks Danny and the rest of the C2 guys!
