I have a 04 gt with loudmouth 1's, with a accufab 75 mm throttle body and plenem, 3:73 gears and bout to get a mid pipe and headers. My questions is when should I get a programer to get more horsepower?
pretty much whenever you feel about it.. i got mine for my gears... programmers dont do much, i didnt feel much from it... i just dont have a rev limiter anymore and my engine runs alittle cooler now from that programmer.
