Fairly cheap and easy solution if you don't have the time and money to take your bike to a dyno shop.
After changing out the exhaust pipes and intake on my bike, it began to backfire rather badly and seemed to run hot (my new pipes were turning blue at the ends). I knew I needed the fuel mapping redone but it when I started researching my options it became overwhelming pretty fast. My new intake is a Vance & Hines model, and they recommended this Fuelpak to work with it. After reading how easy it was to install and program I decided to give it a try. The most difficult part was trying to figure out how to cram everything under the side cover with the ECM, but I figured it out. The bike runs smoother and pulls harder than before. It still burbles and pops a little on deceleration but no longer backfires loudly between gear changes. I think my mileage went down, which is understandable since it runs a little more rich now (for those of you don't know, a freer-flowing intake and exhaust makes your bike run more lean until you re-jet your carburetor or re-map the fuel injection system, which is what this module does), but that's a small price to pay. If you really want to wring the maximum amount of horsepower from your motor, then do your research, get a more versatile fuel management module and take it to the dyno shop. If you want a solution that is reasonably priced, fairly easy to install, simple to program and does a good job of remapping your fuel curves after you've changed your pipes and breather, the Vance & Hines Fuelpak is the way to go.
