Turbo Issue?

[mbatransport]

Thanks for the insight. I have a 09 KW T660 with a CM871. I will look into the slipping clutch first. I didn't know what it meant, so I looked it up and I think it describes best what is happening with my truck. I had a new clutch installed in December.

I did the egr tuneup last weekend and all pipes were ok. Only sprayed the walls with carbon choke cleaner to remove the soot lining the inside walls of the pipes, but I did replace the imap, delta-p, & exhaust back pressure sensors and the dozer injector.

I will also look into the possible fuel issue as well, since I sometimes get a fuel restriction code.
