8.1 Programmers

[[email protected]]

I have 2004 4x4 reg. cab with an 8.1 and the allison auto trans. I have been stock pulling this truck and it is doing very well.

i want to find the best programmer because I know there is still some power left on the table.

This truck is the ultimate blast for pulling. I am like every other guy i want more power!!!!!

I am new to this forum. i really like it.

A custom tune from someone like "BlackBear" will be way better than any handheld programmer.
