Default Lost Performance from Car!

Hey all. I have a 1996 Mustang GT with a few mods on it. (Superchip programmed for Off-road H-pipe, Off-road H-pipe, K&N, and Flow Masters) The problem is that when I floor my car, it doesn't catch on until about 2 seconds later. In the time that it takes for my engine to catch, people pass me up. Does anybody know what the problem is? Thank you.

Stick or auto? Sounds like a tranny problem. Superchips arent exactly the best, might wanna ditch it for a preditor tune.

No, this guy probably doesn't understand that the car has to downshift before it starts making power at cruising speeds... Hence the 2 second delay. Get a shift kit and a tuner and be done with it.

I have 94,000 miles on my car. I do have a leak in my transmission, but I check the fluid levels often. The car doesn't stick or anything, it just seems like it's spinning but not grabbing like it should at about 30 miles per hour. It never did this before. If its not the transmission, do you think a loss of back pressure from that off-road h-pipe might have something to do with it? Thank you.

wouldnt that have to be a huge exhaust leak for it to have that kind of effect?

I still think tranny.
