Interesting that the power has a "dip" between 4600 & 5200 rpm. Wonder if that is the variable cam timing making some changes in that rpm range. Bet a tune could do some good there.
Thanks - again, very good info.

Tuning alone is good for about 26 whp. on a stock car
(taking an average)
Also as for the dyno comparisons, ambient temperatures and humidity were with in 4% of one another, so not much change there, and then the car was at 100% operating temperature each test.
