I was at the track this weekend, and every run I started getting knock retard near the end (fourth gear, mostly). Just trying to figure out what (if anything) I can do to get rid of it for next time? I was using BP 93 octane...mods are:
- catless dp/tp
- cai
- cdfp internals
- 1 step colder plugs
- boost tubes
- rkm bpv
- MAP clamp
- MBC set to 17psi
