okay I get it, i had a 300c hemi back then with diablosport predator programmer, I didnt know if I needed one for the stang too, im aware of the pre-programmed tune they give with it, except since im putting a blower on it, I think ill have to go and run a dyno and ask the tuner to make me up a appropriate tune fitting the blower etc, not sure the reg tune from 91 or 93 with cai is enough...

the borla is definitly a great exaust, but i think it 1.5k$ just the cat back, that doesnt leave me much to throw in header n mid pipe...right?
