That hub dyno is with stock headers, I believe grumpy said he had aftermarket headers with a 90mm pulley (assuming that pulley is an upgrade over stock since he mentioned it) so his should be reading much higher.

Maybe he has catted equal length headers and was running the fully emission compliant tune??? If that was the case then maybe I could understand. @grumpysnapper what headers were you using?
