I just built a 355, already running a supercharger, first problem was not enough fuel for the horsepower the motor puts out, even though I am running 454 TB ported with 454 injectors and a external regulater....so I am going for the Edelbrock Multiport and going to run 44# injectors with it and upgrade the entire fuel deliver system....second problem...tuning through a chip....not happening...so I am going to upgrade the ECU to a EBL Flash....any one running this ECU....how hard is the tuning ...any input will help
