Just retruned from a trip to Solomon, Maryland and used the controller all the way down and back. This controller made the truck really pull great and controlled everything just fine. My trans temp was about 150 with the outside temp at 85 and the EGTs never saw 1100. I'm pulling a 29 Jayco BHS, 7800 lbs and having the power to wheels sooner was a great feeling to have. The trans pulls through the gears great and power was awesome. If you are on the fence about this controller /ubbthreads/images/graemlins/biggrin.gifGET IT! /ubbthreads/images/graemlins/biggrin.gif You won't be disappointed.
