Going to a test and tune tomorrow evening. Wish me luck on the trans.LOL I am going to run 10psi on the 6.0L and see where it gets me until I get my new injectors. I think the DA should be around 200-400 so hopefully I can click off a low 12. I did a 6psi launch tonight on the 10psi setting and my gtech and log both showed 0-60 of 3.96 spinning all four. Any guesses on what it will run?

 

No friggin idea what it will run but am impatiently waiting for you to tell us!
good luck! and have fun

 

How are you getting all 4 to spin? Best I can do is get 3 to chirp

 

55 degree weather and cold pavement probably helps. Last night I launched it at 8psi with my truck weighing about 5600lbs and it spun all four for about 30 feet and scared the crap out of me going sideways. Tonight I launched it at 6psi weighing about 5150lbs and it did the four wheel shuffle.LOL It loaded and unloaded the suspension so many times I thought I was riding a bull.

 

I thought all the 4wds had open diffs in the front... Unless he changed that... And the only way to do that is with a spool...

 

My front diff is stock but for some reason the fronts lock when in 4wd. If I am on dry pavement in 4wd I can barely turn because of all four wheels fighting each other. I have ofter thought there was something wrong with my 4wd but it had doen that since the day pulled off the dealers lot back in 01.

 

2kt, what track do you go to?

 

Cecil.

 

Mine does that too. From what I understand, the front diff is open. I believe that the front wheels can't make up their mind which one is going to drive when they lose traction. At least thats what it feels like, tries to jerk the wheel out of my hand - left, then right, then left, then right...sound familiar? Kinda fun though.

 

Yeah, last night it did the side to side jerk which was interesting to say the least. I had a buddy in with me the night before and he will attest to all four tires going up in smoke.
