The Bog is GONE!!!

[logchain]

MY wife has an 06 m7 all stock it has a lean bog at aprox. 5000 rpms put a can on it made it worse sold the can put on a fuel controll box did not add fuel to the bottem but added a fair amount to mid and a little to the top runs great now, will run right with alot of the m7 with the y pipes cans and air the m7 is well known to be rich at bottem and lean in the mid. its the chits to have to run a box on a stock sled to fix a problem they could have fixed at the factory. hope this helps.,

Mine also seems to have a slight bog in the mid range. I have leaned the low and top end but have never tried to add fuel in the mid. I will give that a shot this weekend and hopfully that is the answer.

Yes I believe you need to richen between 3000-4000. After that watch your plugs and piston wash and start to lean out. Check your clutch for that snappy feeling. Perhaps the belt on secondary is riding too low. I run my with belt sticking out about 1/8".
