Frankly I can not feel any real power gain though lowend throttle response is vastly changed. Where I used to cruise at 13% throttle now it is well down in the single digits and the sligtest throttle movement results in a lot more acceleration because the larger bores allow a lot more are at the same angle. Like I said though no noticable WOT difference. Not seeing anything really different in my MAP or AFGS either.
