Drives very nicely. I just find the idle a little high at 950 RPM and it decrease very very slowly when coming to a light (Before the car actually stops). Power is unbelievable compare to before. Trottle response is a lot quickers. It was fairly cold and the SAE correction was .95. This is a graph uncorrected if anyone is interested to know. Before and after the tune.
Thanx John, I really appreciate all your help. Lot of people are actually surprised that the head were unported. Lots of torque out of this cam.
Both numbers are tuned but one is SAE corrected (411) and the other is uncorrected (430). The RWHP went down since it was very in the dyno room.
