My G35 has 122k miles mostly highway. I have HKS hi power dual exhaust, stillen headers with stillen races pipes, motordyne plenum spacer, stillen lightweight pulleys and an injen cold air intake...i ran it today at the track and my best time was 14.574...i've seen stock G's run faster than that...what could be the problem?...my launch is real slow to, but im not sure whats causing it...

 

The Driver?

 

Ummm...................

Is it cuz you're launching it slow? Lol, dumb question.

 

You need a driver mod maybe?

 

lol, umm OP your not telling us the track conditions, your 60 foot nothing. Post some info!

Stock I did 14.57 but it was 65f

 

^^that

Plus is it a manual, automatic. We know nothing about your car other than the mods.

 

its driver mod. learn how to drive.

 

Is it tuned?

 

+ one as you have leaned the AFR out quite a bit.

 

You need to post the timeslip numbers for better help.

 

mines at 115k

 

tuned?

 

Yeah I think you need to flash your ECU if you haven't and post more info for more help...
