Well, I mixed a little Xylene in with 93 while spraying alky one time in the GN. Ran up to 26 psi with a STOCK turbo and my 100 octane chip and got no knock... didn't run any better, though! I was having problems with my boost control and could either run 21 psi or 25-26. I'm sure 26 is way over the efficiency range for a stocker, but I tried. Wish I could have tried about 22-23, but oh well.
