I would like to do the stage 1 upgrade. I have the Screaming Eagle Heavy Breather air cleaner and the Screaming Eagle shorty mufflers that I would like to install. Has anyone installed these and what type of ECM calibration have you done? I would like something that does not require a computer to install...something that allows these items to be run safely on my bike with slight performance gain if possible...and maybe a cooler running engine. I have been looking at the Power Vision tuner as a possibility but do not know much about it. Is it something that could be preloaded for my bike and then installed by me? I would like something that does not have to be permanently connected. Thanks
