My 92 300sd feels a little sluggish. I have checked the waste gate it seems to work when I slide the arm manually. Had a recent head job and coolant system replaced. The car runs smooth, it just don't have any power. Top speed is about 100 MPH at 3600 RPMs.
Any help Would be greatly appreciated. I'm new to the MB have a lot of domestic experience.
