Here are the 2 runs on the same sheet.
Gray curve is with the CAI intake.
Red curve is with the Roto-fab intake.
Max. rwhp difference in only 5, but look at the large increase in hp in the mid-range rpms (where most of us drive). That's a 25-30 rwhp improvement with the Roto-fab.

Was the car dyno'd with the hood open or closed?
