I'm running the Sidewinder exhaust and Ram Air setup too. I installed a Power Commander and used the canned tune they had for my exact setup. I downloaded it and honestly haven't looked back—it's been about three years now.
I always meant to get it dyno tuned, but I just never got around to it. The bike pulls like crazy as it is, so I haven't felt much need. I went with the Power Commander because nobody in my area was willing to dyno tune a TuneECU setup.
