any ideas????

09 m8 I've been fighting with this for a while now. double checked both clutches,PV, tried different cans, at WOW I'm seeing 7500 to 7600 rpm in powder 30mi track speed. when I back off the throttle to 3/4 and less it picks up rpm to 7850 track speed is 40mi.+ I am frustrated with this thing!!! pulled the plugs thye are very light brown, on the verge of to lean, can it be the TPS tell the ECU faulty reading so it cuts the fuel off at 3/4 throttle?

Make sure that clear tube hanging off the ecu isn't plugged and stuff it downwards. Are the power valves operating properly?

ya I checked the tube. power valves are moving freely. any idea what the proper adjustment should be on those??
