Octane boosters - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Do any octane boosters work enough to get up from california piss water 91 to a decent 93. I have tried all brands of gas to only slight differences.

I finally finished tuning my engine as best I could and have talked to a few experts. My combined mechanical/dynamic compression is to high.

So I want to try better octane booster then parts store stuff which helps, but I do not know a good brand. Or if any truly work. Besides around the margins.

If I can hold out long enough to get things in order I want a LS variant. Or if no temp solutions will work I will do a LT1 350 as it will be plug, and play. Plus I know carbs where fuel injection can throw me a loop I would get stuck on.

This is my only vehicle so I have to play it as safe as I can.
