Just got back from the track
#22
this is i bet alot of your problem,i would go with a shorter tire and alot of guys on here will disagree but i was able to get a 12.59 with a 1.64 60' with 26" mt and 4.56 gears i would go with 4.10 also.te tune could be alot of the problem to at what psi were you running the slicks should be around 16 +/- alittle and just remember it will go up about 2 pis after heating them up.
