Yesterday I hauled 2 loads of 18 1500lbs. hay rolls from Mt. Sterling, KY to Grayson, KY. Not a huge trip, just 150 miles both ways. Had to stop and fill up at a truck stop and decided to run through the scales to see how much I weighed. GVW was 40,500lbs. After that I hit the interstate, set the cruise on 70, and sat back. There are some pretty good hills on I 64 once you get East of Morehead. The truck only went down to 65 and the pyro never got higher than 1300 degrees. Boost pressure stayed at 37psi. I could not have been happier. I was a little worried about having oversize injectors and towing with them, but everything stayed where it should have. Now, I did put the Smarty on CAtcher # 1 and the TST was purely for timing advance only with it on 1/0. Not bad for a 3/4 ton.
