I'm still thinking my car is down on power despite dyno data - nowhere near the 0 to 60 MPH times I keep seeing reported. If anyone wants to try something new and provide me with a few data points, I'm looking for 4k RPM to 6.5 RPM times - stay in 2nd gear the whole time, cruise along at 4k RPM, then punch the accelerator and measure time til pass 6.5k RPM - takes the driver (i.e. launch and gear changes) out of the picture. I'm seeing 3.3 to 3.4s times despite KKM and 2.5" cat back on a non-SVT - dynoed with just KKM at 154 HP - exhaust didn't improve the times.
