Hello, in my 1999 9-3, I have replaced the ecu with an abbott performance as well as install aftermarket blow-off valve, waste gate and a manual boost control. When I set the boost control valve a little higher, ie. when the boost valve goes all the way to the end of the red area of the gauge, the car kicks, and the boost starts over again. I have turned it down before though so it doesn't kick at all, but I do loose considerable mid-range boost. Does this have anything to do possibly with my fuel pump? Is my fuel pump possibly not able to keep up with the amount of boost? If so where can I get a faster pumping fuel pump for times when I want higher boost? Thanks Alex
