I too am a huge SeaFoam fan. Every car I touch gets the vacuum suction treatment, etc -- usually twice a year. The replacement plugs are cooler and gapped to spec. I also have a PCV catch setup. So far, it's performing well at 140K miles.
As far as Intake Air goes, FE is optimal at 100-110F. Under high loads lately, the pinging is very noticeable -- so I filled to a mid-grade mix. The airflow is slower after the warm-air tube to the airbox. This was added later (when the Weather turned colder). I just changed the oil and trans fluid (synth ATF), so that should help. The pinging started after a dead battery cleared the ECU's memory. I may need to "re-train" the ignition system with the ECU bypass method.
I'll have some time to test it this week. It's getting a bit warmer before the next cold snap. Time will tell...
