I just bought a 09 ultra, Had the dealer put on Rienharts mufllers, when I asked about installing the SE air cleaner he said that they are not seeing big gains on the 09's by adding the air cleaner. I, also read read a that on the 09's you can install a aftermarket air cleaner, and exhaust and ECM will calibrate it self.

Has anyone with a 09 installed mufflers and air cleaner with no ECM download?
