Hello, I just installed the SC-Trim on my buddies 92GT and occasionally, when you give it gas, it wants to backfire, or pop, through the blower/maf....The car has all the usual h/c/intake stuff with 24# injectors, and just has the base kit with no bypass or anything. I have the fuel pressure set at 40 and there is an 8:1 FMU plate. Any ideas or suggestions???? Thanks alot!!!
