What kind of dynometer? Thier are many different kinds and they all read "differently" and even that is subjective to the dyno operator.
Honestly, dynos are great for tuning, and "hero" numbers are great, but for real world performance only track times tell the true tale. Always best to use the same dyno for testing and try for constistancy to validate your results. I have many dyno pulls under my belt with multiple cars, and have seen tuning alone on the dyno pick up 100 rwhp on cars (not typical). Many cars will also show their weak points, like slipping clutches, out of balance wheel/tire combo's, rich/lean fuel calibration that you just can't pick up on on the street.
So yeah, I recommend tuning on the dyno, for performance on the track!
