More timing advance. What type of dyno is this on? I would expect 470rwhp on a dynojet, 410+ on a mustang dyno.

I would say your numbers are pretty accurate depending on what type of dyno you ran it on. Some may disagree but Ive always gotten lower numbers on dynojets, but they seem to be more "real". The best test is the drag strip.

You can never have too much power, just not enough traction.
