LOL well from the looks of my times something is putting the brakes on it. I spent way to much on all this to run 15.5 1/4 miles i could have almost ran that with the 4.8 i had in it.

I would hook a scanner up to it, to see why the lights are on.
And no that doesnt sound right, you should be low 14's atleast

Was expecting way more maybe ill get the tune looked at beacuse i have no idea where to start to fix this weak *** setup i have maybe ill just drop it all in my s-10 maybe then ill hit the 13's lol.

Something's up NA my truck ran high 13's with the same cam, up here in Co @5000' elevation. That was with a set of short bassani headers, with stock cat's and intake, through a 4L80E. Would have been low 13's to high 12's at sea level. Is that tune for NA, or boost? What is your timing , and AFR?

I have no idea what my timing is or afr ill have to get ahold of wheatley. And yes my ABS light comes on and stays on,but then sometimes it wont come on at all the parking brake light is on also. I knew yours ran quick with that setup J im stumped but ill have the tune looked at and go from there beacuse im going boosted soon and the setup works great as you know because im using the same as you were.

Im runnig 91 octane also thats what i asked it to be tuned for and all the TQ managment taken off.

One of the next things im going with is a locker gotta get one but the 4Hi launch really nails ya back in the seat . Hey jeff does chris use HPtuners or EFI, i would like to learn how to tune so i dont have this promblem of mailing back and forth tunes for the truck.
