Shit box made 640awhp on a heartbreaker!!!

Took the shit box down to ams today to see where it sat at 35psi. The original plan going to ams is because they had a dynojet. Well it seems they got rid of their dynojet for a mustang dyno... I was not expecting to come anywhere close to what it made on a mustang dyno! After the 640whp I bumped it down to wastegate pressure (24psi) and it still made 499whp! The dynojet number might have been 700+whp! Still a lot more room to go! Can't wait for next year!
