Ok i tried the search but it didnt give me the exact answer i was looking for so what im asking is ive got an 06 banshee all stock except, open lid, k&n, and t5's. I just got a adjustable timing plate and want to advance to +4. I need to know what the max compression is before i need to run a more octane gas. I believe ive read anything above 150, but wasnt sure. I currently run 93 octane. Thxs for any info, its greatly appreciated!!!
