I just happen to get a great deal on the PCV and SFM and Yoshi R77 titanium SO and a lot of other stuff brand new still in the box, so I figured I would put it on. I originally was going to get the Bazzaz Fi (I already have the Z Bomb on it) because it tunes all the injectors with just the single unit but I ran across this great deal so I thought hell I'll give it a shot. Plus there's absolutely no one around here (Chattanooga) that runs the Bazzaz set up, that I know, so getting it tuned or even getting a generic map for it may be hard to do. I want to have a tune for my bike that makes it perform at it's best at every RPM range in every gear. If the SFM is not going to help with that then I don't want it but if it will then I do. I talked to tech guy at Dynojet and he said that it would help ut that is his job, you know. Is there anyone on here that has ran their bike without the SFM and then with the SFM? If so please let me know what you saw as far as performance changes or problems. Thanks everyone for your help. This is something that I have no experience with.
