2006 M7 not holding rpms

[rohdeiv]

My M7 is hitting real hard off the line, pulling around 8,000 rpms. Then as I start to climb it dies off and doesn't come back to 8,000. It seems like it is loading up a bit too. I am running around 8,000-10,000 feet if that helps. If anyone has any suggestions I am listening.

Had similar problem with mine......Check the power valves....just did mine last week. Made a big difference after cleaning them.
