I assume that the higher I go in RPM, the more strain on the belt which could cause slippage.
Charlie, Brown, Could the belt slipping cause the trim code errors? I replaced the belt two weeks ago. I am going to pick up a tensioner tomorrow and see what that does.
Thank again for your help.

That is not how you diagnose belt slip. If your crank and your pulley were exactly the same size, then I would say you could do that.

Look for belt dust under the blower pulley, glazing on the belt, listen for belt squeel. Watch your boost gauge. What does it do? Does it stay nice and steady or jump up and down?

Check for unmetered air or leaks in piping between blower and intake.
