I have a 17 axys 800 with a Mtntek kit and I have a bog that I’m trying to chase down. When I first installed the kit, it ran perfect around my shop with no bog from just off idle to straight wide open. It was a used kit and the fuel lines had some wear spots so before the first ride I replaced the rubber fuel lines. I’m pretty sure it was just a coincidence but from then on it’s had a bog if I go from low throttle to wide open. It only does it after being at low throttle for a little bit then going onto boost. It seems to be running rich under boost then when I get on it again it takes a second to clear out and run right again. I’ve checked tps, new plugs, new maf sensor and new relays. My egt probe connection was a little loose so I crimped it back together and that made it a little better but still there. Also, the people at Mtntek have been awesome to deal with and the quality of all the parts is great. Sean has been great about trying to help me sort it out, but I was hoping someone here had ran into a similar issue and figured out what it was. I might change out my coil packs next and see if that helps. Gremlins suck, especially when it ran perfect, then after changing something so simple it starts doing this.
