Also, If all checks iout the CAC "might" have a hole in it. Yes, check ALL the piping. My 8.3 lost a boot & it feels like it has 1HP! LOL

After reattaching the boot & tightening all was back to normal.

Oh, Do you have an Exhaust brake & could it have stuck closed?

I do have an exhaust brake. It appears to be operating correctly. I feel/hear it kick in at the appropriate times as well as the indicator light turns on.
