I had Brazel's RV dyno tune my Workhorse UFO Gas pusher almost two years ago. I didn't want to post until I could get some time and miles on my Coach to be sure and accurate. I have a 37' Winnebago Latitude. What I can tell you is very positive. It runs so much better and their is enough change in the power that its like having a different engine. It used to almost immediately shift down on any hill. Now I go over many hills with no shifting below 4th gear. It seemed like I was always in third gear before this work was done, unless the road was flat. I averaged before the computer tune up about 5 miles to the gallon. I now average a little over 6. Where I live in Oregon every place I go is up hill over the cascade mtns. or coast range. We will be going sever thousand miles this fall so I suspect it will improve more. Jon at Brazel's is a true expert at this and I have used him for all my upgrades. They all have made me feel I got a true value for my money. A condensed list is Koni shocks, high temp spark plug wires, laser alignment, changing fuel filter to off the shelf ones, maintenance work including lube and oil. I actually take a day to get there and a day back to have them do the work and I actually feel good about it.
