Default Killed at wot
I bought this car for real cheap but it ran great up until WOT. It is a full bolt on car with long tubes and a borla catback. It also has a 150 shot dry kit(nos) came with the car. Problem is after replacing plugs, wires and the opti, it still is sluggish as hell when you really get into the throttle, and when you hit wot it just about dies. If you let off a litlle bit it will pull out of the stumble and pull well. Why does it fall apart at wot?

Sounds like lack of fuel to me.

Go get a gauge from Discount Auto or whatever, and see if the fuel pressure drops when you get on it.
