Made several more dyno calls with no luck. One place which is very popular with Porsche folks in the area showed a dyno on their website, but a call found that they got rid of it; guy still thinks one of his techs could tune it without a dyno, but I’m picturing one tech driving while one tunes and me paying two techs! For a much more time consuming tune than on a dyno where trouble areas can be isolated and easily repeated.

Yes, in my old Piper Saratoga (plane), the rule of thumb was to run rich to cool the engine. But I think all bets are off when we change the intake and 'efficiency' (read work) of the engine due to the ITBs and electronic fuel injection. I thought about putting in a front mounted cooler, and still may, but as you note - pricey.
Sorry to hear of your tribulations on getting a dyno run - I'm actually amazed how difficult it is, so I assume there is alot of maintenance and/or tech costs that make it prohibitive. I guess the iterative trial and error approach may continue for a bit of time for the both of us. For the time being I'll be out there in the mornings on the weekend recording and analyzing and making tweaks based on my 7000+ ft altitude.
