I have an opportunity to pick up a Ness Big Shot controller off Craigslist nib for $100. Is this unit the same as VFCIII - Dobeck etc? I'm not looking for any performance gains here, just trying to improve driveabilty and reduce backfiring - popping on upshift and downshift. I have disconnected my 02 sensors also. The bike runs well otherwise. I will not be getting a dyno tune anytime soon as I live in Alaska! What do you guys think? Good deal or save my money?
