Do you need a controller?
  • Yes, if your bike is stock and running jerky around town... she's lean and needs more fuel.
  • Yes, if changing your exhaust from stock and want to get the most from your pipe purchase.
  • Yes, if upgrading intake or air filters and want to have your bike run safely and properly.
  • No, if you think adding a controller to a good running bone stock bike will make it go faster.

Review: If you had a 10 rating it would still be to low. I installed this on my 2005 C90 1500 CC Boulevard over the weekend. I didn't change one setting. Installed an open air filter and drilled out the center baffle. THAT'S IT.. All I can say is (WOW)!! It doesn't even seam like I started the same bike. If something ever happened to this controller I will cry. And immediately order another one. It is that good. And the free patch and flashlight where a bonus. Thanks GMan

Review: Ordered on Sunday, received on Wednesday and installed Thursday. Very simple installation. Could not believe the immediate difference. Vance and Hines pipes sounded better and the popping stopped. Big boost in acceleration. I would definitely recommend this product.

Review: Hi GMan, I just want to say a big thank you and let you know how pleased I am with your product. I purchased a 2007 Suzuki Boulevard C90T with Vance and Hines after market pipes. I had a lot of de acceleration back firing and bike was running not as I would have expected.(rough). I did some research online and found numerous good feedback re your GMan Bully . Being stuck down under in New Zealand with limited options I thought that I would bite the bullet and give your product a try. I purchased... More details
