like 23psi, I ran 2 gallons of 104 octane mixed with the 6 or so gallons of 93 octane.

 

^^^I broke into the 12's with the same amount of boost as well. I just wanted to compare with someone who basically has the same mods as I do. I was on half a tank of 92 octane when I did mine. I haven't been able to repeat it since it's gotten warmer out here though.
