Hey chris,
I have a 427w and on the stand it was 525hp at the flywheel and on the chassis dyno it was 427rwhp at 6000rpm. Should of used a 6500 chip instead as the numbers were on the rise when the rev limiter kicked in. Builder said power would curve at around 64-6500. he said could use a 6500 to 6700 chip no problem.
