Well got the tq management out, put in a billet servo and went to the track.

Old best in 2600 ft density altitude

60- 2.26
1/4- 14.54
mph 93.67

New best last night in 2441 density altitude-

60- 2.26
1/4- 14.25
mph- 96.67

It ran 14.26-14.34 most of the night consistantly.Almost hit 97mph.

 

I don't know your track set-up, but when I put 20's on mine I lost almost 1/2 a second and another 2-3 tenths on top of that when I switched to 22's.

 

Yeah that's what I've been told..when winter comes around I'm hoping to get some take off wheels and maybe I can get the the track with them. Sounds crazy that 20's slow you down that much but it would be cool to pick up more off a wheel swap.

 

So, how does it act w/o tq management & a billet servo? Does it shift real hard or what? I fixing to have the same thing done next week.

 

Pretty nice really, nice smooth shifts under slight throttle and hits 2nd and third HARD! Barks second every time. Funny to watch the tach when it shifts..it leaps from 45 to 55 real fast! It's just what the doctor ordered!

 

That's awesome! Did you firm the shifts with LS1 edit any? What rpm are you shifting at?

 

mark the truck felt awesome! it was sick that 2-3 shift! thanks for the ride
