I just want to jump in here and say HI to Bill and his fan club!
I had not been successful at finding anyone who could crack open the DiamondStar Logic ECM until I ran across Bill's Orion Reflash about 6 months ago. After about 2 minutes of reading, I threw my money down.
I use my 4700 LPX as a hotshot tractor pulling a 40' gooseneck trailer. I haul lightweight freight out of the Kansas City area. At 175hp I knew I'd have super reliability out of the T444E but after a few months of having to crawl over nearly every overpass I encountered, I was about to give up on the truck and find something else.
I run the truck on the 230hp tune and it is phenominal! I can load it up with freight and it'll run 70 mph all day long!

Big thanks to Bill and his team for unlocking the potential these M/D trucks have.
