Hey guys so im new to the Mustang game and just bought a 88 Supercharged notch. has a bunch of work done and trying to find a good tuning idea to make good power and decent driveability. How much power can u make with the stock ECU with a SCT chip. the car apparenty made 560 with a chip for start up and a anderson pms for everything else but it might have went bad. it drives like garbage. pig rich and throttle when warm and runs really hot. seems like way to much timing. any help would be great. thanks
