Bill,
Your post is a little hard to follow, but I've had something similar
happen before on a couple of occasions and both LNC4P's had the old fuel
selector which has been known to let air into the fuel system.=20
Depressurizing the cabin cleared up the problem on both occasions, and
after rebuilding the fuel selector, the problem did not come back.  One
of them would surge even with the low boost pump on.  Going to high boost
would make the engine run fine too, and switching to the other tank would
run better also.   Just an idea of something to at least look at.=20

  with the TSIO-550B engine, which has 450TT and 220 STOH. We had been
  tweaking the baffles and checking the CHT probes by swapping probes 5
  with 3 and 2 with 4. We had just seen a great improvement in CHTs
  with the modifications. I was in the process of climbing to FL220 to
