Who is running the PPE Xcelerator on their LB7? I want to get one, but I am trying to get feedback on what the max I can run in with my stock Allison. I currently run a 135 Quad with stock, but I drive it very careful, and have ZERO problems. What are you guys running with the PPE 160 tuner?

He is right. You will need one someday. I have the Xcellerator and is has been from 120 to 210. Has towed a fair share and pulled a sled 4 times. It wasn't junk but you could tell 5th wasn't right so its in for an upgrade right now.

Even being careful, there may be times when you are doing a full throttle 4-5 shift which is the death-knell for the Allison in stock form. Contact Mike L for more info on this. He is the great DP Tranny guru.
