I got in 14 runs tonight, the track got empty towards the end of the night... My previous best was a 9.8 @ 75 w/ 2.4 60ft (8th)... Tonight I ended up with a 9.47 @ 75.96 w/ 2.3 60ft (8th)... The changes were 4.10s, TrueTrac, shift kit, and a better tune.. The 9.8 run was @ 35* and tonights temps were 40-50*.... All in all I am happy with the little 4.8... The crazy thing was on my 1-2 shift it would lose traction, not bark the tires but spin them bad.. My logs show my mph goes from 44 to 66.... Check out the pic from my log, I highlighted the shift, noticed the min and max values......

Next to come will be a small converter and then the turbo...

looks good man! might want some DRs too! your traction issue only goes down hill from here

what size and type of tire are you on?

I am running 265/70/16 general grabber UHPs... It hooks at the line but spins on the 1->2 so I am thinking it is in the tune... on the 9.4x runs the truck would shift to the side a little bit... Maybe it was just the track prep...

could be track prep, my camaro would spin a little on the street, but at the track i always had to let out on the 1-2 so i didnt slide sidways into the lane next to me.
i had stock rims with 245/50/16s
you could tune the trans to shift softer but i think its time for drag radials

Yep drag radials would be nice, but I dunno if I want to speed the extra money... I am saving for an engagement ring and a turbo sooooo, drag radials would just be a luxury... I am going to try lowering my shift pressures some and maybe add in a little more TQ Mgt. to soften up the shift a little more... The funny thing on the street it just chirps the tires, at the track it spins them...

nice man, .4 tenths is a good gain, congrats on the new times man!

I don't think you're really running fast enough yet to need drag radials. I'd work on the tuning and fix that shift issue. More stall would fix that.

That is what I was thinking, I am not making near enough power with the little 4.8 to need DRs.... I do plan on working on the tune thou, a little less pressure at the shift and a little mor TQ after wards....
