got a question, i've got a 93 auto and i'm lookin into gettin some sort of piggyback system. I don't really care what brand just as long as it works. I've got a ported engine, open 3 inch exhaust, bosch 255 fuel pump, intake, upgraded radiator and i/c, and greddy profec b spec 2 boost controller. I still need bigger rear injectors. my question is other than going complete stand alone, what would be a good setup as far as injector size and an ecu. and would it be possible to tune it all myself? any input or suggestions would help. thanks!
