Well no luck with traction in EITHER 2wd or 4wd. 2wd I smoked the tires through 30mph, then backed off the throttle to let em grab, put it back on the floor and still pulled a 7.4.

4wd was still slipping a bit, but not completely breaking free. ran a 6.3 in 4wd.

For what its worth, this tune needs some SERIOUS help. I was logging AFR vs RPM vs MPH. The AFR looked like OJ Simpson on a polygraph.

 

That 6.3 sounds more like what you should be running. What kind of A/F did you log? Lean, fat or just all over the place?

 

Running 35" tires you need a 4:56 gear to to tame those bad boys. You'll also see a mileage improvement after you get over playing with the new gears... lol

 

I see a roll pan in someone's future..

 

all over the place ranging from 12-18 in a CONSTANT up down up down up down just like a polygraph or richter scale during an earthquake

 

Thats why I only do roughly 1/2 throttle til 30-35 then go from there. Anymore and I get a little squirley. The offroad type tires are not really sticky though and a good WIDE set of street tires really helps a lot up to a certain point. When I had the same tires I have now but in a 275/55/20 I could only do 1/4 throttle launches, after the 305/50/20's were put on it made it so I could go half throttle launches.

 

Is that at WOT only or are you seeing that at part throttle too?

 

IF I did not owe on my taxes this year and did not have to sell a few things I may have gone that rout, but sh*t happens.

 

Driving around town I notice it moves a LOT, rarely even in the same whole number for more than a second at a time. During these WOT runs, I started the log at a stop, ran 0-75 in 2wd, came to a complete stop, ran 0-70 in 4x4, came to a complete stop then stopped the log. total time was about 1:28 and it was going crazy the entire time. really no steady trend at all...

...i've GOT to get some datalogs sent to Marty.

 

Wow thats no good if its at WOT. Mine runs a constant 12.4 at WOT so it can still be adjusted a little but there is no KR at all.

AF have you logged for KR? if your WOT is running like that I'd guess that it is probably knocking bad
