Got the new dyno up and going, needed something to pull on it. So we tried one of our shop golf carts on it. Made some adjustments and picked up 1 hp. Sometimes small gains make a difference.

Matt Engle brought in a very cool looking 60 Ford F100 for some dyno time and tuning. This had an awesome patina and a good all around look. It was powered by a fuel injected 5.0. He’ll get alot of looks out of this one.

Mason Reber’s 14 Mustang GT in for some dyno time and tuning.

Gary Yetter’s 19 Heritage Softail in for some tuning. We changed up some exhaust mods and added baffles to the exhaust. These M8’s are very sensitive to exhaust mods and can easily be over exhausted and its a common problem we run into. This bike cleaned up nice with the tune.

Congratulations, Ray Brown won the McNew’s Choice trophy at the South Mountain Mopars show in Carlisle Pa. We couldn’t make the show so they designated someone of their choice and it ended up being Ray. His GT350R with a wide body kit and Whipple Supercharger. It was a surprise when Ray showed up and asked us to sign it. A very nice car and very deserving of an award.

46 Chevy brought in by our friends at Posies Street Rods. This small block Chevy powered truck came in for us to tune the Sniper Fuel Injection. This was a nice ride and is a driver that the owner uses and drives.
