I have a knock sensor and controller installed from KnockSenseMS but I have found that it is not effective due to engine noise. I would definitely consider the J&S system though. So far, I have not had any knock issues that I can identify and I have regularly inspected my sparkplugs. However, I did start off with a super rich tune and worked backward from there with AFR's of 11.0 now at peak boost with the methanol. I can certainly say that you loose a lot of power with AFR's <10. I don't see much increase in charge air temperature with this setup.
