Power Lag 2011 Summit

[snowmed221]

I have a stone stock 2011 Ski-Doo Summit 800 E-Tec.
The power seems to flatten around 7000 RPM, then really kicks in hard again around 7800 to 7900 RPM. I've seen a few posts about this, here and there, but no one seems to know how to fix the problem... Either I've missed it, or no one knows... What are your ideas?
