Review: Been using this controller for over 6 yrs, I gave GMan the air and exhaust I'm using and he emailed back the codes, never been touched since, they will always have my business, fine running 900, thanks!

Review: This is long, but its worth the story. I'm on a 2014 Vulcan 900 Custom running a V&H Slash Staggered (2:2) exhaust and an open intake (pick one). I ordered the brand new Cobra PowrPro Black (May 2016) as it was supposed to auto-tune the bike constantly. My bike just didn't perform well from idle to throttle or from cruise to heavy throttle. I called Cobra and their support told me this fancy auto-tuner didn't like my exhaust and that my exhaust was causing my bike to lose power.... well isn't that funny... an auto-tuner that claims to support any intake and any exhaust and to tune it to the best settings through any environment... well... BS. I came across some forums and heard some things about GMAN and his amazing customer service . GMAN responded to even the simplest questions I had and attempted to provide advice for my other controller while I was waiting for the Bully in the mail. I don't commonly rate a product a 5, but this is getting an extra star specifically for the way GMAN handles their customers. The controller itself fixed every bit of hesitation that I was having and I'm back to a solid feeling bike. If you need a simple controller, you'd be hard pressed to find something that is this close to set it and forget it. I'm not one for a dyno, and I don't really care for getting every possible HP or lb of Torque out of a cruiser, so I cannot give you absolute numbers. What I can tell you is that the bike is running optimally and its never felt as smooth as it is right now. Its also worth noting that I may have only lost 1-2mpg after installing the big 3. If you're on the fence. Get this controller and don't look back.

Review: I removed the FI2000 and replaced it with the GMan Bully in hopes that the aftermarket exhaust popping would be resolved. Not only was it taken care of, but the power the bike has now is amazing! Great product and only about an hour to install. Definitely worth every penny!

Review: I got my Bully installed and what a ride. Thanks, Leon Apple

Review: My Bully Fuel Injection Controller arrived in great shape. Thanks for the terrific communication throughout the process. Hope to do business with you again. Patrick

Review: I purchased the Vulcan 900 Bully a few weeks ago. Install took twenty minutes, I felt the throttle response and the torque right away. With modified stock air intake and exhaust there was still some back firing on deceleration, how ever the bully did reduce th back firing by about 80%. I purchased an after market exhaust and put some miles on the Bully. After spending some time with my Bully I was able to adjust it to decrease my back firing almost completely!!!! My gas mileage is better, but I have not tracked it to find out by how much it has increased! GMAN thank you for the great product!!!
