Hey guys. Need some advice. Got an 08 xp, full motor rebuild about 900 miles ago, 860 with rk tek 14:1 heads. My last trip out I had some issues with the sled, from what I'm seeing on here it sounds like I've got rave problems, going to take the sled in to get codes read and cleared anyway. My big problem that I need to solve is I spent the whole trip retightening spark plugs. At first I thought it was just the new plugs but after tightening them twice I started to figure out I got other issues. I have loosened plugs before, but never noticed it very often, but this trip got ridiculous. Ive always mixed minimum 50% c111, this trip I was at 60% because original plan was to try out the nitrous. My main jets are 440, and are what I've run since the build. I picked up some 460 mains and am going to try that but looking for any advice or info you guys might have. Really just want to finally get this thing dialed in perfect! I have been told my mbrp can needs to go, and probably pick up a skinz can, apparently the mbrp creates back pressure with the 860?? Wasn't aware the can had any affect on back pressure but rk tek recommended getting rid of it. I know this is long but really hoping to hear how other guys are set up. I also want to get some controllers hooked up for some monitoring info, so any advice you guys got there would be appreciated. Anything out there that monitors anything with nitrous? My boondocker kit has a regulator, but would be nice to see hhow much is actually getting fed.. Thanks
