well there are a lot of issues of why its that slow...
1. 4.8L but they can be fst with the right setup..
2. 97lbs 20" wheels
3. 200lbs ******* bed cover
4. no converter - i couldnt even launch higher than 1500rpm without the truck creaping foward..
it needs tuned again i know that for a fact...we dynoed it on sat and the air/fuel ratio was all f-ed up... my tune guy got the harness stolen from him for the program so i plan on getting it tuned again real soon....next time also i will remove the bed cover and remove the 20 for my 17" centerlines that will have a light tire on them...as for the stall im still waiting to hear back from fuddle on which one i should go with.... ill get those times down...if not this year definatly next year when the 496 gets dropped in!!!
and i was thinking last night that the motor just might be dead....i dont know on the dyno it has right now with a half *** tune 264rwhp....my guy says he can get over 300 with it when he does it again...
the first tune i did was with now exhaust just straight headers and no front o2's...back are deleted!!!
