Just as a checksum, we took the car out on the road and ran it to the normal 6,200 rpm fuel cut-off RPM limiter...
Either way, the max HP was generated at 4,785 rpm.... 184.5hp then dropped off to 112.6 at 4,857 rpm then 113.7 at 4,930, then 100.9 at 5,002, then 70.7 at 5,075 rpm with identical air / fuel ratios of 14.4.
I've read somewhere or saw it on a DYI auto show, that this is a problem with a lot of cars with traction control so there is a 4 wheel dyno that keeps the front wheels running at the same speed as the rear. Maybe you can find one of these dynos in your area? just my 2 cents.
