What Customers Say About Don Performance

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!! ?

Benjamin Waldeck
Don Performance Customer

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.
