I've ran it out to 9600 so far; I was running into knock issues with the IAT2 getting so high on the dyno.
The chambered 2.5"-2" zzp exhaust didn't help either
Soon as I bolt the 3" dp and catback on I'll rev it higher

Yea i found the threads. Pretty cool! I'm glad to see someone actually running legit supercharged high compression pistons. Our ratio is a joke for what's bolted from the factory. Seriously, 10.5:1 is way better. Has anyone tried 11 or 12:1 on this platform yet?
