My name is Rob and i have a 2010 VStar 950 Tourer that I have been modding. After a lot of research I decided to add the Cobra Slip-On muffler, the Cobra PowrFlo Air Intake, and had Ivans Perfomance re-flash my ECU. I bought the bike used with 7k miles and it already had the Cobra Slip-On. I talked to Ivan and discussed what he recommended and he said with his ECU reflash and the Cobra PowrFlo, that you really didn't need a fuel controller, that it would be wasted money. Anyway, I got all the parts yesterday and intstalled the intake and ECU and took it for a joy ride down Pacific Coast Highway to Long Beach. The bike now accelerates smoothly with no backfiring and has instant power when you twist the throttle. It is amazing how much better it rides! If you own one of these bikes, I cannot recommend this setup any higher!!!
