Power Loss
 

I have a 2000 Gt and I took it to the track when it was stock. I ran 15.010. I went ahead and bought a cold air intake, steeda racing pulleys, bbk xpipes with no cats, V-force muffles and a shifter. I know it aint much but when I took it back to the track all I could pull was a 15.100. I wasnt expecting to pull 10s or anything just atleast .5 off or something. Anyone know what is wrong I would appreciate any and all help. Ty

Do you have both time slips?

What were your 60 foots as well as your 1/8th mile stats in comparison.

You could very well be looking at a difference in temperature and humidity between different days.

I threw them away. Kinda pist after I left there. My buddy has a 2002 gt and we hit the light the other day and we were even to about 2nd then 3rd he started pulling alittle. Is there anyway that by putting these mods on that i would have to tune it? It just seems I lost alittle torque and if i was supposed to gain hp i should of caught him in the higher gears. ty

According to my sources, 2001 and below GT mustangs came with a 3.08:1 rear end. In 2002 the engineers became smarter and upgraded to a 3.27:1 rear end. This alone could be the difference as to why your friend with the 02 beat you at the end regardless of your modifications. I just put a Ford Racing 4.10:1 ring and pinion set in my 02 (I know for a fact it had a 3.27). WOW! What a difference. Additionally, anytime you purchase a "canned" programmer as I call it, you are getting a generic overall chip upgrade that based on R&D of the maker, works best overall, not factoring in modifications. Take the car to a specialist. Have the unit put on a dyno. Invest in a Superchips custom programmer and have them develop the curves for you specific to your setup. This is the ony way to get maximum out of your vehicle. Every engine in every car whether it be a Mustang or anything else, varies from engine to engine. One 4.6 will generate 260HP in testing when assembled while the next will generate 268HP. It is a law of human tolerance. After you are done, sell the canned prorgrammer on ebay and make up for your losses. By going to a specialist, you will develop a realtionship with that company and they will cater to your needs and desires. You will be much happier. Each time you make mods, they will tell you if it is worth your while to re-dyno. Even if you do, the charge is minimal and the improvement is in your favor. The initial cost factor is in the custom programmer. My people at Kisor Performance in Cincinnati charge approx 350.00 for the programmer and then 35.00 for each program. They dyno tune and charge 100.00 per hour if you choose to go that route instead of the generic prgram curves. Return adjustments for upgrades are for the dyno at the hourly rate, power curves included.
