Product Reviews

Review: It does what it says it will. I have a M109R with 6K miles on it and drilled stock pipes. After the pipes were drilled they sounded better but I got the lean surge. This plug and play device fixed the problem. Mounted under seat in the tool pouch. Since I'm not going to dyno and I don't have O2 sensors this is all I need. Might play with the fine tuning, might not. All in all a good device.

Review: Awesome!!! Had one on a Suzuki M50, one on my burple 06 and just ordered another for my 2008 M109R w/only 275 miles..... excellent product!!

Review: Great Product!! Works awesome. Higly recommended!

Review: I installed the Bully EFI controller. Holy sh$%* what a difference. I also opened the intake and put short radius Freedom Exhaust pipes on. I haven't even hit the fastest setting and I love it. Throttle is now smooth with no dead spots and the performance is great! Excellent job on the controller!

Review: From a stock bike to changing the air filters and modding my exhaust I chose this controller. I have not had to touch the setting yet but I will be having a play soon. Defiantly smoother power delivery through the gears and combined with the TRE works very well. Again great customer service and feed back from GMan. Many thanks Gary, much appreciated!

Review: I've had a Bully on a Suzuki M50 so I knew how they worked,,now upgraded bikes to M109R and went again with the Bully......awesome!!!

Review: After my power commander crapped out the second time I thought I'd give this a go...great stuff runs a lot smoother.

Review: It has out performed the power commander that I had installed since 2008. PCII crapped out on a long bike trip, had it removed and continued with trip. Got back home and installed the Bully controller. What a big difference gained 2 miles per gallon. Now has more power to lift front wheel when I shift from 1st to 2nd at full throttle
