In towing, I pulled Bills 6.0 on a tandem axel up monteagle (5 miles of 6% grade) at 60 mph running 900 to 1100 EGTs. The truck and trailer combo I would guess is in the neighborhood of 10,000 to 12,000 lbs.
Pulled 80 to 85 mph over rolling hills with out breaking 1000 degrees. I am impressed with his ability to tune these beasts. The other tunes I had couldn't do that.

That is great to hear! I ran a couple other tuners before I started working for Bill. I was happy with the other tunes and thought my truck was quick.. Then Bill got ahold of my ECM and wow. His tune filled in the dead spots in the other tuners and really hauls in comparison.
My tires have taken quite the toll.
