Hi guys, its been a long time. I had to put my 89 Daytona Shelby TII in storage for the past 2-3 years, due to the combination of my situation and the gas prices. Anyway, last Friday someone totalled my economical daily driver by rear-ending me at a stoplight, so I took my Daytona out of storage and I've been driving it since then. My situation is that I drive roughly 100-120 miles a day and buying 93 octane is killing me. My question is what would I have to lower my boost down to in order to safely use 87 octane? Its just a factory, unmodified engine with a BOV and a grainger valve. Any input would be good, any experience with this would be great. Thanks in advance! :thumb:
