004 2500hd 6.0 extended bed, 4x4, plow package, no mods as of now

15.45 at 89ish mph with a 2.26 60'

I couldn't believe that these things run this good. I was going to be happy with a 16.00 slip

Now I think I'm going to have to throw an intake and a converter on it.

Whose and what size stall converter have you guys been using??

Also you can really tell that TQ management is killing these things, what programs are out to eliminate this.

Thanks for the help

Brian

Go with Nelson, you'll be happy.
