Jannem, you could try an EGR gauge (home-built airplane shops like in the Los Angeles area have them) to see why your idle air bleeds are affecting your cruise engine temps. EGRs can use either thermocouples or thrmisters. Thermocouples typically have a very slow temp response but are cheap while thermisters are very fast but expensive. Both can be about as accurate. Normally, one only needs one sensor in each header collector, with a selector switch. That would make a good Pantera tuning article.
