like I said before , a NSX he tuned here made around 470whp , and on the dynojet it made 550 somthing whp , that is around a 17% differnace , just duing a 12% gets me to 501whp and using the same 17 the NSX saw it would be more like 524whp or there abouts , this is on 18lbs , and at 20psi we still spun tires on the dyno even with slicks , it is hard to strap the car down on the dyno...so again no clean runs , cody is sure the car is well over 500whp on pump at 20psi , hell the plugs still look good on 22psi and nocks are in check but the dyno does not like it , but before this he had never had a fwd car make over 350whp on it
