WTF?!? I got it from American Musclebrand new.it is the diablo predator tuner.
It says that the car already has a tune when i go too load one.Would that be the tuner or my car has a tune on it already?? It says it when it trys to back up my stock tune.
You have to go to Ford and get your PCM reflashed with the stock tune.

it sounds like timings off. My timing was off and my car ran like ****... Yes, I ran my car with crap timing for a week or two (because I didn't know what it was), and yes, I gunned it prob 5-10 times during that and the engine is still ok (thank God), could have been a *****-or story.

anywho, its good to get a tune and a mid pipe (since thats the biggest bottleneck of our exhaust) and you'll be good.

or just get that cobra and be done with it all!!!
