Check the Lycon site. Occasionally I hear rumors that they are working on
an STC for the IO540s in our Aztec. From what I understand, they would put
a red line on the MAP which should not be exceeded and this would protect
the engine from exceeding the HP rating. Like I said, this is simply hanger
talk but you may learn something from a phone call.

Thanks Jim, that was my view. Just don't use full throttle near sea
level. I can live with that trivial operational restriction.
