Good idea ! I ran 110 mix w/93 this past summer at roughly 12-14 psi , I bought an alky control kit , because I was scared of bieng on the edge

.

Damn I wish I had 20psi of boost ! Having rode behind 20-21 psi I will tell you it's insane !!!!

Man you got me wanting to turn up my new turbo bad!! I don't have meth, just pump 93. 12 psi with 16* for me right now with no knock, so I may pull a degree and bump it up to 14-15 psi
