No, never had any kind of engine trouble (knock on wood).  I don't like
to advertise this since RRE is busy enough as it is w/o someone blowing
an engine, but the honest answer is that I've been running ~20psi on the
street w/ pump gas for at least a couple years.  I used similar
reasoning- I figured if the EGT's were good, if timing seemed fine, and
if the car felt faster at 20psi than it did at 19 (and 19 faster than 18)
then everything seemed to be happy and I should enjoy it.  I didn't do
this until I felt my fuel system upgrade was complete and I had a good
FMIC, regardless.

I have kept my AFC settings a little on the conservative/rich side, I
suggest you do the same.  I don't think my EGT's have hit 900 since April
of last year.  Wherever your ideal settings appear to be, try richening
up by 1-2 clicks for at least the last couple knobs.  Losing a few extra
horsepower is a small price to pay compared to running on the edge and
risking damage.  Run on the edge at the track with race gas.  For the
street, stick to being on the rich side.

P.S. - Do yourself a favor and avoid the AVC-R.  Stick with a trusty
PRofec-B.
