Acceleration Hesitation
 

from a stop when i start to accelerate it starts really slow and then it starts to speed up after about 2500 rpms i can't do a burnout(even when i hold the break and i cant get above 2000 rpms) in first gear but i can bark gears going into second for some reason. I am not getting the power i should be at the take off. I was wondering whether what would be causing this....perhaps the timing? I am not sure...Also i would like to know would whether it would be better to just take off both catalytic converters or just replace one that is broken?

What mods do you have? some mods can cause some serious powerloss in the lower end. Get some gears, thatll send you flying out of first

The only thing I could see killing your torque is the E303 Cam. But it should make "that" much of a difference, especially with your gears? (did you mean 3.73's? 3.43's are an unusual gear)

Have you dyno tuned it BTW?

the guy i bought it from said they were 3.43's so i guess thats what they are and why would that cam kill my torque.......no i have not had it dynoed

The E303 Cam makes the peak torque much higher in the RPM band, which is good for increasing HP, but sacrificing your low end torque on the street.
