If you want maximum power, get it tuned for the highest octane that is readily available in your area.

If you can swing the gas money go for the 91-93 tune. That will be the best way to get the most out of the cam.

And after you datalog still run 87 as you won't detonate on it anyway. Not enough compression or camshaft issues stock to really detonate. I run 28 degrees of advance on 87 with no knock...
