Vent time,truck is just to danm slow/gutless mods in sig and off the line for the first 75' I could run faster.No power brake burn out no nothing they are finaly buildeing a 1/8 mile track so i will be able to compare with normal times but I will have to take a lunch cause this thing is slow.any other ex cab 4x4 guys feeling my pain? One more thing was reading post about people doing crank relearn after cam/tune even though they have no ses or obvious engine nosie qusetion is why?

 

The crank relearn after doing some reading is that the sensors on the cam shaft and the crankshaft need to be resyncronized(sp?) so they dont show random misfires. You really need to get a tune and that will wake it up. Just out of curiosity what are your times. I run a 15.1 na quarter, 10.1 1/8th with a TCI 3000 and with the nitrous a 9 flat in the 1/8th which converts to a low 14 second pass. My truck when it was running right would get up and go pretty good off the line and with the nitrous would spin all four for about 3 feet coming out of the hole but now Im battling misfire issues so Im about ready to give up.

 

throw you a 3k stall and some 4.10's in the rear and that thing will wake up. also a good custom tune

 

Stall, tune and ditching the flowmaster should be your next step IMO.

 

My Bad fixed sig .Already have nelson tune.1slow track well be done in sept then ill let you know.

 

We need to start a "i give up thread" for all of us pissed off in general with our trucks!!!!! I feel your pain, man!!!!!

 

Took your idea and ran with it.

yea the tci or yank is definately one of the things you need to look into so that cam can come a live and be at a good satnding rpm when you live the line but dont think you are going to be racing from a dead stop with street tires.
