the motor side is pretty straight forward. the trans side can get a bit tricky. most of it you won't touch. tcc side mainly. there is some motor side tweaking that does affect the trans. remember that part. when you remove torque management on the trans side. be very stingy on how much you remove. contrary to what you read on the hpt forums. it is there for a reason. lowering shift times, upping line pressure, shift rpms. these trans can take a fair bit of abuse, but there is a fine line. you'll know it when you cross it.

Last night we both reset the fuel economy and drove 40 or 50 miles to the track running 70 with cruise (just to see the difference between the two). Went and ate in town thru several lights and mine was on 19 and his was on 18.6!!! Pretty good!! I had a trip to new Mexico and on te way back running 75 got 19.7!!! That's good mpg to me and running 8.90's!!

Yalls trucks are running a little faster than mine but its pretty close. I found my time slip.. not sure this was my best run but I think it was one of the better ones. I did this full weight with a tool box full of tools in the bed and a 200 pound passenger.

60'- 2.1697
1/8- 9.2
mph 76.32

Not "tuned only", but my best 1/8 mile pass to date is 9.349 @ 76.91, with a 2.238 60' time. Mods in sig.

Pretty sad, but Pat will "git 'er" figured out whenever I make it back down to Victoria!
