2.15 60ft indicates a pretty slow take off. Are you doing a 4WD boosted launch? Is that turbo lighting quick enough? What RPMs you turning at the finish line? Doesn't sound right. I've never run my truck but I used to do a lot of bracket racing and I don't have 1/2 of what you got in your truck and I guarantee I can hit a high 15 in my truck (well after I get a tranny that is).

Well something isn't right. Even with a 2.6 60' I can still run a 16.1 at 88MPH. and that was with just an Ez and my injectors. with a six speed to boot. Like ^ said are you doing a boosted launch in 4wd? To my mind 35PSI is a little low with the fuel your putting to it. Maybe your wastegate is opening too soon?

NITROUS and a 3rd gear boosted launch. with th e4.10's you're not gonna be very fast. find someone to swap you for some 3.54 and you'll pick up a bunch i promise. you should be in the 14's. what clutch are you running??? what's your charger measurements??

Is your tranny stock or aftermarket? I would start looking at that next I think. For a boosted launch you should have a faster 60' time than that.

That torque converter could be slipping. My triple disc only lasted 9 months. So just because you have aftermarket transmission parts dont over look that as the problem.

Sounds like a boost leak, or a weak injector pump.
