Well...I found the de-fuel thanks to Nick at Duramaxtuner and it has an enable/disable button in the TCM.

What version of EFI Live software are you running 2500 HD?

i just downloaded the latest one, but i got 01 lb7 so my stuff is a little different

Mine's an '04 LB7. Only difference between our tranny's is the "G" solenoid in the valve body.

im missing a few tables too, with my 01ecm and tcm

Have you tried downloading your TCM tune since you got the new software?

nope, not yet did you get new tables?

I'm not sure when those tables showed up because I haven't had use for them. I downloaded the new software about 2 months ago. I've had EFI Live since March.

same, i dont touch my tcm though and my defuel was taken care of in ecm tuning, but i might have to take a looksee if anything has changed, i havent read my ecm/tcm in a while, i just replash alot

Kewl! Well I learned a bunch today so I'll be doing some enhancing on my tune now. I fully expect 12's in a couple of weeks when I get to the track again!

Hey....thanks for you help through this man! I owe ya few cold ones as I had the de-fuel about gone with your advise!

i can see 12's in ur future, ur truck hauls some ass, if you play with 2nd gear launch u can drop 2 tenths off your et, but dont use tow/haul when u do cause u can burn up ur convertor cause it locks in 2nd with it on.

i dont think i can hit 12's anytime soon, my pump is getting weak, i can barely hold 21kpsi with a 24kpw, and it just noticed my sustained rp is getting less and less over the weeks :(

but good luck with the 12's
