Couldn't agree more!! Nothing Dr. Allen cant fix.:thumb:

Keep the 4.10's!!!!!!!!!:burnout:

I think you don't have enough resistance for the turbo to spool up with 4.10 gears. The shifting is a tune issue. The gears may hurt your times, b/c your truck is so light. I could be wrong, but most turbo trucks like a little smaller gear to give the turbo a little resistance. With 31 inch slicks, a 3.73 is as low as I would go with a turbo, now n/a trucks with a 31 inch tire, I would go with a 4.56.
I could be wrong, but that is my two cents.

I'll try and make it to the track Friday to watch you run, since Allen will have the truck torn down.

Thats what I think James, everyone at ls1tech says the same.
