Everything you're saying here makes me think the timing is off... either the mechanical timing is off or you're not properly setting the ignition timing. It's also possible that you are squeezing a little more power out of it but not safely... Don't run at any significant advance without higher octane fuel, it's begging for a rebuild. Yes, the ECU tries to pull ignition advance if knock is present, but it can only ever pull or add so much, you're shortening the systems safety net.

Also about the octane booster...87 plus..lets say a good octane booster...that will be sufficient for fuel? I gotta take advantage of my free 87 gas situation .

If you want to stick with your free fuel you gotta be willing to toss in $10 of toluene with each tank. Remember, the octane booster ALWAYS goes in the tank BEFORE the fuel; That way it gets properly mixed in.

I prefer MCC, a bit nastier. For a thorough clean you may pull the spark plugs and spray in a good amount and let it sit overnight; Just spray in enough to fill the piston domes. Most of it should be evaporated by the next afternoon and it will be hard to start after you put the plugs back in.
