Craig put Comp SPR Stage 2 cams with springs into his 07 GT. He also deleted the CMCVs and has LT headers. The car made good power with no loss in low end tq.
The limiting phasers were also installed and VCT was locked down to 18* of max retard in the tune.
I spent quite a bit of time getting the cam retard right for these cams. This was a case of more is not always better. There were some big gains to be had in TQ in the 4000-5000RPM range by having the right cam timing. I was also able to make the curve much smoother.
I believe craig has also logged some great gas mileage.
