There are a lot of good ones out there, try searching for Air/Fuel Controller in the search menu for the forum. But if I might ask what exactly are you going for in your car?

with the 3" down pipe i have the boost is now higher then stock, 8-9 psi, and i cant give her WOT without the car hesitating. i can feather the throttle up and down but if i keep it floored she cuts power.

Have you checked to make sure you didn't accidently unplug a vacuum line from the wastegate?

If you are only hitting 8-9 psi it might not be fuel cut. I think it kicks in at a little higher pressure. Are you using an aftermarket boost gauge? The stock one isn't very accurate especially above 8psi.

When you keep it floored it cuts out? In gear? Have you checked for any codes?
