I am in a quandary here with my 09 Ultra with Monster Ovals. I am thinking of installing a HD Stage I kit (part# 29260-08) but I am hesitating on the HD ECM download. According to the 2009 motor accessories book, SE section, the ECM download says: "Recalibration is required for proper installation, and will allow the bike to rev up to 6200 RPM." OK I not really too eager to rev my motor past 4K RPM, much less 6200 RPM 1. Stage I kit is 50 state street legal - no warrantee issues going forward 2. ECM download recommended - per above "recalibration to match performance pipes" 3. Screaming Eagle pipes, when added will match steps 1 & 2 above. Now being aware about all the discussions about warrantee issues on this forum with some SE performance kits and third party "FUEL TUNERS", I called and talked to the one of the local service manager and discussed my options, and he said Stage I kit is OK, and will not affect warrantee, he also recommended the ECM download and SE pipes. When I mentioned that I have the V&H Monster Ovals, he said oh that's kind of a gray area and may not match the Stage I and ECM due to non SE pipes. We then discussed the use of third party "fuel tuners" and he said it will definitely affect and void standing warrantee as this is products represent tampering with EPA requirements. So to cut through the chase, and to stay within the legal bounds of my 2 year warrantee: - Can I just do the stage 1 kit and forgo the ECM download since it does not match my V&H MO anyway? Will this kit make an already lean bike leaner? - Or do I just keep the stock air cleaner and wait until the 2 year warrantee expires and let go crazy on the PCV or V&H fuelpak?
