Don Performance

Had the Don performance tune carried out my local HD dealer in the UK after a stage 2. From cold the bike's fueling is perfect and pulls really well. Very impressed indeed 👏

Absolutely recommended for anyone who rides a Harley Davidson. I bought a new Fat Boy and, after some discussions, decided on the remapping. But driving all the way from Berlin to Bremen? Yes! Definitely. The service and advice over the phone were already very good. But arriving there was a whole different experience. I was warmly welcomed, everything was explained, and all the work was carried out precisely and cleanly. A heartfelt thank you to the entire team. Superb work. Thank you so much!

I've had my mapping done by Don for a year now and I'm still thrilled with it. A visit to his site confirmed my impression and the final result. He's a great guy with a wealth of technical knowledge, and he takes plenty of time to explain everything and much more. Awesome!

Guys... ☝🏻 I absolutely have to get "something" off my chest!!! It started with the fantastic, long 5-6 phone conversations, which were sooooo precise, informative, and detailed that I didn't sense any disinterest whatsoever and immediately knew that you guys are just as crazy about perfection as I am 💪🏻☺️. I bombarded you with so many questions, and you explained everything down to the smallest detail, even showing me how the function changes and improves. Because how awesome is it not only to feel the increased performance while driving, but also to understand what you, Don, have so dr
