M8 Cutler stage 2 turbo, bogs at low rpm

[Brojoe]

Hey, I have an 2010 M8 with a stage 2 Cutler turbo. I ran it this weekend for the first time at elevation, and had a bog right at 4000 rpm, or just after it engaged. I am not overly experienced with 2 stroike turbos, and i could not get rid of the bog even after I adjusted the attitude box. Could this be turbo lag or clutching? I changed the plugs, and the clutching,weights etc. came from Cutler? Any info would help. Thanks

I just installed a stage one on my 2010 and have same issue in hard going and not because of powder plugging exhaust. I have made it better by raising my red blue and lowering fuel pressure but i am leaning on clutching now. I am going to give dale at cutler a call and hopefelly can help us out.
