Hey, just thought I'd drop a bug in your ear and say, remember that air=horsepower, fuel+air=more horsepower, and all the horsepower in the world won't get you an inch without proper traction. The way it is now, can you stomp it, get grip, and GO. Knowing mustangs, your answer is probably a resounding "no". Think about that. Too many people today are obsessed with horsepower, and dump tons in their motor, and then get their ass waxed by a 300 horsepower import with all wheel drive. The only differece being that HE got traction, not out-horsed, or out classed you.....just traction....just a thought brother, if you need any more advice, you're in the right place....peace....and happy hunting.....
