i have a 2000 gt 5 spd and my father had bought same year car but when he got his the guy gave him a SCT tuner with the car my dad didnt care much for the motor cause he was swapping it right away, so the car he bought had the same upgrades as mine, catless x pipe,catback, throttle body, CAI, coils,injectors. i wanted to use the tuner that came with my fathers car since he had no use for it and i know how when you buy a tuner its can only be used on the car you set it up for, so i thought why not swap the computers so i can use the tuner? i did the swap today and when i put the old one in the my car it wouldnt start. do i need to hook up the tuner with it or is this not possible at all? i had work so i put my old one back in since i didnt have time to mess with it.
