Ok, general question about mustangs. The 02' GT's do 0-60 in 6.0s correct?

Well I have the following modifications:
SLP LM2 Exhaust
Ford Racing 3.73 Gears
C&L Cold Air w/ MAF
Diablo Sport Tune
(Car has about 14000 miles)

For some reason, no matter how many times I try, I always get around 6.5-7.0s. I really dont think that any of these mods have help me any if not at all. I weigh approx 200lbs. The car has brand new tires. I can do it countless times and have some where it's done perfectly (perfect launch, perfect shifts, ect). It almost seems as though the car was faster stock. Now i have to shift to 3rd before i hit 60 and it pisses me off w/ the new gears. Am I just seriously that bad of a driver? I've been driving a stick my entire life and more than enough drag experience. Can it be I'm not timing myself correctly? Could it be I've installed a bad tune (how exactly do you do it?) Where should I shift (I've tried all through 5-6.2k and no help)? Also, my car feels like it nearly dies after it gets to about 6k. Is this normal.. Like literally, no accelleration.

Thanks,
Vicente

 

That is a lot higher 0-60 than you should be at. It is definitely gonna feel like it's dead at 6K with it being redline. I usually shift right at 6K or slightly below. All I know is there is a problem somewhere for sure, I am just not sure exactly what.

 

How are you timing yourself?

 

I was also wondering the same thing[&:]

 

if your doing everything perfectly then i would say that you have done a bad tune.. you do it your self? when i get mine tuned after my cams i am going to take it somewhere to get it tuned just to be safe

 

I'm just using a stop watch holding it in my left hand. I feel that i should be accurate +-.5 seconds. I seriously feel like its slower than before i added my mods. Could it be a bad MAF or something? I really want to know whats up.

 

actually the power band in that engine is right around 5800 rpms, if you slam the gears right around that you should get full power into your next gear, I also think with 3.73's you should still be in second at 60. Also a power curve on any car goes up as it approaches redline, then once it leaves the power band (Greather than 5800) the car will start to lose power. You should be running mid to low 5 second 0-60. Dont time it yoursef, have a buddy sit in the car with you and do it, ahah that might be yur problem too

 

My best 0-60 on the GTech is 7.3 with the pi parts and crazy bad traction. Was a 7.5 before. You have lower gears, maybe worse traction problems? Temperature?? I still think high 6's on the street is right.

 

how you hitting third at 60?

 

I do have a friend do it too.. I'm almost embarassed to have them sit w/ me.. The car is PERFECT, it runs and rides nice. I've tried shifting at multiple points. And my car reds at like 50 in second. Should this be true too? I set my gears in the Diablo to 3.73 gears. I know its accurate at 25ish cause i go by the stupid radar thingys and its dead on. I really wanna figure this out.
