Fuel controllers — so I’m at the point where I’m past-ready to 1.) get rid of the backfire, and 2.) get any improvement in throttle response, smoothness, idle control, etc, etc… but also after googling over fuel controllers that I’m curious which controllers really do what… and of course on a 570, which platform is worth going to based on limited returns for the $.
Alba would seem to be the most popular on the forums for 570; it can eliminate backfire and gain a couple HP with a muffler change; there’s the Power Commander which would have more adaptability but does any of them make that much over the other? Can you control idle speed ?
