I'm not sure if I'm more impressed with your numbers or the fact that James was actually at work when he said he would be

Sounds like you're having a good time with it. The trans is slipping already?

trans is fine, numbers were run on street tires, and spray.

and James wasnt there... i had to phone in an appt. lol

i need to figure out a better location for my nozzle, i am not getting the full effect of the 100 shot i have in it. i cut the nozzle yesterday so it would shoot straight at the MAF, but now it hits it so hard it shuts the truck down. damnit! the nozzle is about 9" away from the MAF?? i dont understand it? if i spray under 4K, it shuts it down, over 4K and it runs like i stole it!!

You could just by a seperate IAT sensor ($21) and mount it near the TB opening and the put your nozzle after the MAF...

that is a pretty good idea!

i am getting a decent hit, but not all 100 horses. i ran a 9.3 n/a, and the 8.58 was on the 100 shot..... so it dropped me around 7 tenths... not too bad, but i would figure a 100 shot should be around 9 tenths drop at these slow speeds.

I wonder if your freezing the opens in your MAF screen and causing a blockage in your intake...

If you going with that tall of tire in the future I would definately get 4.10s... However if you like to speed it does push more RPMs, my GF commented today, "Are you still in 3rd, it sounds like your truck needs to shift", this was at 70-75, pushing 2200ish RPMs, so the exhaust noise is noticeable...
