Id richen it up a bit more if i were you to LOW 11,s. dont even bother with the afc for a knock reading, its very inaccurate… just keep in mind that ur probably very close too/maxing out those 370`s so before u decide to run more boost, invest in a meth injection kit,start off with a small nozzel(m7-m10) and work ur way up to a bigger size as u tune for more boost.
Pay attention to ur base timing, redline etc and go to the dyno!!! based on ur dynograph u will know if ur getting any ignition breakup and also what rpm your power/torque falls off… great work and good luck
