I have a 2010 HCR that was a sponsored race sled that I picked up. The owner said the motor was ported then sent to Arctic Cat and dyno’d and they downloaded a fuel map for it with the stock pipe and snopro airbox. I did a little research and see that the race sleds have hill climb ecu’s so wondering if that’s what I might have here. It runs strong but I like to mod things. I picked up a Jaws single pipe and y-pipe they say doesn’t require a fuel map. Any harm in bolting things on and check plugs. How hard is a boondocker box to get dialed in if I need one? Where do I start I’ve never run one but understand that I may need to add fuel. I ride 3k to 7k. That hcr track sure spins a lot it’s got to go.
