I'm already have a Stage 1 kit with a HD filter installed on the bike - if I swap out the filter with a K&N (HD-0800), will I need to adjust the F/A ratio? With an increase in air flow, it seems I'd be running a little leaner. Assuming that I'll need the engine remapped, would it be worth investing in a Power Commander or TFI? I'm comfortable working on this stuff, but I haven't a lot of experience and my garage isn't set up for this. I imagine this topic has already been covered, but my searches didn't find answers to these questions. Sorry for any unintended redundancy. Regards.
