With my boost at 9lbs. and no cooler should I run higher then 93 octane fuel? This car is not a strip car just mostly cruising with a race here and there. I was wondering if I should just add a little vp motorsport 103 to up my octane a little. I have a very nice water to air cooler but no money to buy parts to install yet. This cooler is also pretty big maybe to much for my set up so i may be interested in selling or trade.
