Jim Buckmaster was the Old Tuner Guy. He built the business having been in the high-performance and racing industry for over 50 years. During that time that time he built street and racing engines, modified thousands of carburetors and distributors and reprogrammed the PCMs on the newer computer-controlled cars and trucks.
He was involved in many aspects of motorsports including Drag Racing, Oval Track, Ice Racing, Truck Pulling, Tractor Pulling, Sand Drags, Mud Bogging, Off-Road Racing, Road Racing, and Demolition Derby competitions. One lesson that Jim lived by is there is no substitute for quality components or quality workmanship. His goal was to strive to provide both to the best of his ability.
For the last decade of his life, Jim was focused on helping customers with over-the-road applications and working with owner-operators and small fleets to maximize the performance and efficiency of their engines. Unfortunately, Jim had some health issues and he passed away a few years ago. We have tried to carry on the legacy that Jim provided to us to continue to provide quality components, quality workmanship, and quality customer service.

I pull a 53' dry van with a 2007 Pete 386. On March 30, 2012 I had a single turbo conversion kit installed on my Cat engine. The kit looks great with the ceramic manifold and the polished turbo. Immediately after the installation I noticed a lot more power and the engine runs a lot smoother. The engine is also running cooler than before as well. Before installing I averaged 5.99 MPG over the previous 116,419 miles. Since the installation I have driven 15,620 miles and I'm averaging 7.28 MPG. I drive about 2500 miles a week and this system is saving me $283 a week in fuel savings. I'm very happy with the kit.
I am happy, happy, happy! I absolutely love the additional power, but the 1.1 MPG increase in fuel economy was the real reason that I bought the conversion kit. I got everything that Jim said I would and more in the bargain. The truck runs so much smoother too! I didn't realize how bad my mirrors were vibrating before, but I can now back up and actually see where I'm going!
I have a 2006 Peterbilt 379X with a 625HP C15. I pull heavy trailers including double drop stretch trailers that haul over-sized loads. I installed the single turbo conversion kit in May, 2014. I have never averaged over 6 MPG on any of the loads I have hauled since I got the truck and I was told that I would never see good fuel economy out of this truck with a 625 Cat. Since I installed the kit I had a lighter load where I average 8.2 MPG over the entire trip. I can safely say that I have picked up 1 MPG since installing the kit. I have put the truck on a dyno and it is putting 701 hp to the ground. I am tickled to death with the horsepower gains and everything else. I also have a 2005 550HP C15 that used to get better fuel economy than my 625, but no more. My next move is to install a single turbo conversion kit on that truck as well. I highly recommend the single turbo conversion kit.
We haul rock on mostly short runs with our trucks. We installed one of the C15 single turbo conversion kits and the truck increased from 4.2 MPG to 5.2 MPG. Before we installed the conversion kit, the truck was scheduled to go into Cat because there were several oil leaks that we were having. However after we installed the kit the blow by was reduced so much that oil leaks disappeared and we canceled the appointment.
