I run 15.34 was my best. I have a 2.2 60 as my best.


Sounds to me like he needs gears, shorter tire maybe or still have some TM in the tune
TM is all off bro....3.73s are his gears

Sometimes I think I get better traction on the street than on the strip. If I mash it from a dig on the road I might bark the tires but usually just hook up and go, at the track I know I spin here and there. The only explanation I can think of is asphalt is rough and easier to bite for street tires than the slick track with rubber layed everywere...who knows Either way his 60's are way off compared to his ET's, are you sure he's hooking good at the track?? Let him borrow a set of slicks for the track maybe.
yeah bro, he's hooking pretty good...he's used his 26s, borrowed 27s, and even 28"hoosiers....it's a badass cam, TSP 224/224 .581/.581 112 LSA.

+1 It is all about gearing. Driver mod? Does he know how to launch the truck off the line? Maybe he just needs to learn how to drive the truck. Don't take that personal, but it was what came to mind. It sounds like the truck is running good.

that's definitely not it bro...that truck has been ran by many drivers at the track already, all very experienced drivers and none have been able to make it run better.

Maybe he has a lot of knock retard on launch. Have you scanned any of his runs?

take it out back and shoot it.

but really, stay away from the track, just continue killing unsuspecting victims on the street.
