Goal
1-Don't redlight
2-Don't breakout
3-Run consistanthttp://www.duramaxdiesels.com/forum/images/smilies/spit.gif

Try 4Hi.....I tend to think you will have too much torque multiplication in 4lo with those tires.....but I am just taking an educated guess. If you can try both.

Well after 4hrs of trying to get the timing system working (tower side) we finally got to run our qualifying run. no pre stage lights on the tree. my dial in was rt=.639 et=5.936 mph=57.3. three hours later 1st heat i broke out lika sob rt=.645 et=5.651 mph=62. So after the qualifying run i switched from the 150hp to 100hp tune thinking it would help keep me from breaking out. So much for that. the truck pulled a lot harder on the 2nd pass. I didn't log any but i'm willing to bet that the ghost in my fuel system struck again (intermittent rail pressure) I wish they would go back to heads up class racing like it was 10 yrs ago. I was king of stock 6cyl for a few years with my little 93 s-10. I'm pretty sure i could have beat all the cummins trucks there last night

So did you run it in 4Hi or 4Lo? I assume it was 4Hi?

How well did it hook?

4 hi worked good. I added a video to my Sig. Traction wasn't to terrible.

Wouldn't you run out of gear at 62 mph in low range?

I realize it's after the event.
