Hmm? Sounds like an ignition issue.

   You should be able to add MP to about 31.5 - 32" with great success.
That would give you about 17.5 - 18 gph in GoFAST mode and still be
adequately LOP.  Above that MP, LOP, we have noticed that soem engines
simply won;t run smothly even with exceellent F:A ratios.  We have not
identified the cause.

***  Although I have limited time on my new TCM TSIO-550 I experienced
the same roughness when at 32" and leaned back.  Runs smooth for a while
and then shudders for an instant, then smooth again.  I've not
experienced that with my Lyc IO-360: it runs smooth leaned back nearly
to starvation.   ***
