Rock on. Right at 550 to the tires.

Good data here, I assume that the 3rd pull is before jet changes, in the same trim as it was when you dyno'd it before? That seems to be the general correlation between a Mustang dyno and a Dynojet...I've seen 5-10% numbers, this one seems to reflect the former.

Do you know the A/F ratios between the 537 number and the 549 number? Bumping it up 12 horsepower to the tires is a good bump for a few jet changes.

Kudos to Jay and Brian.

BTW, I've seen Jay dyno in several different configurations....hood up, air cleaner on, hood down, air cleaner on, etc, etc. Which was this?

Look at that torque curve baby!
