Thats pretty pricey, I think you could get the same effect and then some with a good air fuel controller. Of course the Air/Fuel controller will cost about a hundred more but I think its a better buy in the long run, especially if you're upping the boost. Simply raising the fuel cut level of the engine just sounds dangerous, more so for track only applications if any.

Do they make a HGD? That might be more useful. Pros: car will be faster Cons: not for long. The money is better spent elsewhere, besides aren't those things from the 90's anyway?

ok so what's a good Air/Fuel controller?

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.

yes after market gauge. old one replaced with volt

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