the differences I explained in post #9
basically easier to get it in and out of lean burn. and you dont have to be super careful w/ the throttle to keep it in lean burn. i've been driving on the FED ECU for a few weeks now, and my initial assessments were spot on. i havent noticed much different since then. i keep modding the aero on my car, so its hard to say highway MPG of FED VS CA ECU. but once i stop modding the aero and get that settled, then i will be able to do a 1:1 comparison
