although i'm not "special" like many of you w/ the superchargers (i wish i had one), i feel guilty seeing that almost everyone of y'all who posted uses the higher octane levels, and I use the lowest that i can get. It'* to expensive to get the good stuff.
by the way, do all of y'all hate shell?
Kevo, on a basically stock SSEi, 91 is fine. After several mods, you'll notice a preference for 92. I run 92 now, as 91 just feels sluggish. Funny how one point of octane can make a difference with a few mods (it was the Jet Stage 2 that did it for me).
