LB7: Best Way To Leave The Line...

[RobsDmax]

Well hooked this weekend at a local pull and ended up top ten, which was fine by me, first second third were all 700 HP plus, I leave my truck in 4lo, in 3rd gear and tow haul on, and the truck seems to defuel hard 2-3 and drops some momentum. Any ideas?

Have your tcm programmed to start in 3rd gear. I had mine done a couple of pulls ago and works great.:thumb:

Ya i was thinking that or a fast shifting TCM tune. Only thinking fast shift because I am on stock trans still! :roflmao:

I leave in second roll out about 20 feet and giver her hell I am stock fuelling and turbo I usually do pretty good that way

TCM tune to start in 3rd is the way to go. Build a little boost get it rolling then pin it to win it.

 

[RobsDmax]

that will be a bit harder on the stock trans though right?

 

[duramaxzak]

Eric (wisconsinhick1) is who programmed mine. Probably be a little harder on it, but shifting under heavy load is not easy on it either!

 

[RobsDmax]

fair enough! i will maybe do some fiddling with this weekend

If you need help let me know I'll do what I can.

Leaving the line depends on the track . I personally build as much boost as I can then let her rip most of the time . But on a bad track sometimes you need to get the sled moving forst .

that would be awesome. I have the stock trans tune for my other 03 Im guessing it should be ok to use in my other 03

Yes sir that would be a good start. You'll just need to apply your trucks VIN to that TCM tune.

My DD stock fuel and air I still start in 1st and usually just hammer it off the line. It's usually pinned in 3rd gear converter locked 10-15' out. 60% of the time it works every time :rofl: I get no defuel.

Yes very doable Been running stock trans for two years now I do have a converter. 4th gear starts. Ran 3rd gear starts in my LMM on stock trans and stock converter for two years also
