What is Dyno Tuning?

While we have performed all kinds of work on Harley-Davidson motorcycles, our true passion is making them run better. In our dedicated Dyno Room, equipped with a Dynojet 250i, we do just that. The Dyno is a tool that we utilize to help us determine not only what the bike needs to make power and torque, but can also help diagnose issues like slipping clutches, oil sumping, detonation, air flow issues, etc. We’re highly experienced in tuning both carbureted and fuel-injected Harleys. We have used several different tuning systems over the years for EFI bikes, but our recommendations these days are Power Vision and ThunderMax. At TPT, we pride ourselves on delivering a custom map tailored specifically to your bike, unlocking its full potential!
"Took my bike to get a new rim and tire put on before I left for a 5 day trip. First of all, he fit me in with a short notice. As I was leaving his shop, the bike started sputtering. I drove back to his shop to see if he could find the issue. Even though it was closing time, he went above and beyond and stayed 3 hours past troubleshooting and figuring out the problem. After figuring out it was the fuel pump, he installed a new one. If not for him, I would not be heading out on my trip tomorrow. My hats off to all the guys at Twin Performance Tuners! They made me a life long customer! I highly recommend this shop!"
