i got a 96' GT and am going to get it dynoed/tuned in around 2 weeks or so, all it has is aftermarket exhaust system and 75mm throttle body/plenum. what power increase could i expect a tuning would give me?
-thanks

 

maybe 10-15 rwhp

 

Dissapointing isn't it? Without a SC or gas a 4.6 is a high 13 sec car at best. I aded a tuner, 4.10's and a manifold back exhaust nand with my new 315/35's in the rear I may get a 13.999 if I can get a 2.0 60'. Wrong platform to go quick. Shoulda saved for a Cobra!

 

i just tuned mine with diablosports that u do in 5th now ull do at 500 rpms less i used to do 75 at 2500 rpms now i do it at about 80 at 2000 rpms lot more throttle response and actually rip the tires a bit

 

Would you please explain that one as i have the Diablo Predator and i am not sure what you did? What parameter did you change? mark
