91EmeraldGLX

Alright, So today I drive my friend's '87 Gt. Which is mostly stock. And then I get back in my '91 LX, which has headers cold air, pulleys, and an aftermarket exhaust..Yet for some reason my car didn't seem to accelerate like his does..Anyone have any suggestions as to this may be? Maybe my engine isn't tuned properly??

Were you a passenger in your buddie's car? If so acceleration would appear to be better because you didn't know when he was going to accelerate. Have someone drive your car while your a passenger and you"ll see what I mean.

No, I was actually driving my friends car. and I noticed the difference in acceleration in 2nd gear around 1.5 grand on the tach

Perhaps the rear end ratio's may be different.

There can be a noticeable difference in acceleration even with cars that have the same power.
