The HP thing on the aero is a joke, not even close to what the real numbers are.

It will measure inlet temps pre-blower, not after. So say its 70º going in and after the blower prolly 150º +. But you cant help that all because its a heaton blower. Only an intercooler can lower temps big time after blower.

Ive never done the engine load one, but at freeway speeds you will prolly see when the car is running at 68ish mph the rpms will be at 1900-2000 and 30-32 ing. advance, thats when you would be at your best fuel economy at right around 30ish.
