West Coast and Don Performance create a completely new road riding experience with bespoke mapping for your Harley-Davidson - it's like your own personal Dyno session. Using your existing set up, whether you have a standard ride, stage 1 or more modifications, we'll take your engine performance to the next level.
With 5 years work into research and development, Don Performance created an engine-friendly optimised map to deliver the smoothest delivery of power, whether at slow speeds or under throttle, the ride is consistent and even results in cooler running.
Very competent advice for Harley riders from Bremen and around who want to get something out of their engine without damaging it in the long term. In my opinion Bremen's best Harley tuner.

Best address for someone who wants to optimize his Harley, that's all. My Streetbob is no longer recognizable. It couldn't be better. I'm more than enthusiastic. I've tested a lot beforehand.. All rubbish against Don Performance!! ?

103 Big Twin with open air and J&H. Ran very unevenly with the 08/15 mapping, many misfires when coasting. After the mapping of DP now the cream of the crop. It's great that I can also call a long time later and have all my questions about tuning, StageKits, etc. answered.

We've trialled several of our own bikes and as the UK's Premier Don Performance retailer we're more than a little excited by the results. Available for all fuel injected models including the Revolution Max engine, it's an industry first.
