Ok, so I purchased the predator tuner for my 05 gt and installed the 93 race tune that was on it. My car has full magnaflow exhaust w/ xpipe, long tube headers, 3.73 gears, C & L racer CAI, no cats. Now is there a custom tune i can get from a dealer or something for more power?

 

A custom tune, even if it's canned, will get you some more power. The problem is finding a good place that works with the Predator. Pretty sure Steeda can get you one for around $50, TMS member price. Custom dyno tune usually runs around $400.
You can modify the tune yourself for the 3:73 gears really easy, same thing for wheels/tires.

 

Contact www.americanmuscle.com for a Predator tune. Bamachips now operates out of AM and they support the Diablosport tuner. I have been running a Bama tune for about 5 yrs now and they are well worth the money spent.

 

I thought they would only support the predator if you had already purchased one of dougs tunes before he teamed up with american muscle? On the site I only see tunes for the trinity am I looking in the wrong spot?

 

I only see the Trinity too, pretty sure they mainly support SCT now.

 

I would seek out a reputable shop that does good work on mustangs and get a custom tune where the technician can personally run the car on a dyno and actually see the car himself IMO

 

Ooops, you are correct. They will only support Diablo if you had purchased one before. My bad, sorry about the miss info. I do remember that when they originally went over to AM, they were supporting both formats but I guess they stopped.
