I guess its just simpler to look at the gains made to discount dyno differences.
Dinan's overall gain from just a stage 2 tune according to the original published works is 342-296= +46 whp gain sooo...
Has anyone seen a 46 whp gain or more?
335whp = 368 crank hp at 8.9% drivetrain loss.

to check my math 368 crank - 0.089 * 368 = 335 at the wheel (i rounded by 3/10th of a hp).

quick way to do it is 335 wheel /.9 = 368 crank.
