'The Bully' is a very simple to operate, user friendly Fuel Injection Controller designed specifically for the Suzuki Boulevard C90 running either the Stock Exhaust System (stage 2) or a less restrictive aftermarket exhaust system of your choice (stage 3). ‘The Bully’ requires the use of the exclusive K&N air filter, the GMI-1598 and can be purchased separately or as ‘The Bully Package’

(Model specific for C90)

This addition (Bully & K&N filter, I already had aftermarket pipes) made the most improvement for the least money of anything I have done to my 2005 C90. The GMan web site shows a + 22% Horse Power & +36% Torque increase. I purchased the these items thinking the web site was advertising hype but after installation I am convinced the figures are accurate. The bike is like a totally different beast. Thank you GMan

I like this controller .I had a few problems with setting it to my exhaust but GMAN worked with me to solve the problem . Ha if you get cobra speedster shorts you can't get all the popping on decel out!!!! Exhaust flaw not Bully Flaw!!!!

Easy to install. Easy to adjust. No more popping on decel, and quite a bit of boost compared to stock when you get on the throttle. Stage two right out of the box worked perfectly for me. Fuel economy before the "Bully" was about 42 MPG. Fuel economy after has been about the same, or slightly better. My last tank was 45 MPG, and that was mixed commuting, throttle twisting, and cruising.

When I rode easy it gets great milage. When I roll on the gas It takes off like a shot. Best of both worlds.
