Nelson Performance is going to take care of the tuning and wiring for me...i dont wanna risk blowing another 60e...i thought it would be a good upgrade as a stock unit plus 2 extra gears with my 4.56s should help me on the highway haha.just wanted to know what stall the 6spd guys are running
cool good to know,,,would u know what gear the 6spd guys are finishing the quarter in?yea im gonna see how she runs at the SAR LS1 TRUCK shootout with the 4.56's...i also have a 09'sierra denali 2wd of course it has the 6spd in 1st gear it'll hit 40mph so im guessing ill hit 20mph lol

I wouldn't worry about 1st gear with the 4.56, that is depending on what your rear tire dia is.
What RPM, speed and gear do expect to be in when when your cross the finish line, is what I'd be worring about?
I have a feeling your effective rear end gear ratio will be 3.87 with a 4.56 rear end in 1/4 mile.
Don't think effective rear gear ratio will be 5.24 instead.
I can't remember for sure but I think GM recommends not exceeding 6500 RPM with 6L's, could be couple of hundred lower even.
Should make for an interesting 1/8 mile short track drag truck.

I think you should really think about it. With the 60e you are running about 13.9 to 1 first gear with the 6sp you will be around 18.5 to 1. you are going to shift before you get 10 feet. I'm running 2200 with a basically stock LY6. With 29" tires and 3.00 rear. It's no race car but I shift before I get across 4 Lane intersection. 1st is 4.03 to 2nd is 2.36 a big step. Now what about the TCI 6speed from a 4L80e?
