Ok my best friend just turbo charged his neon, he has a built block etc. And is currently in the process of breaking it in. His question is.. When boosting more than normal one should A) add more fuel B) retard more timing C) retard timing and stay way rich at top end D) let the MSD boost retard function do its thing, and lt the RRFPR do its thing and crank the boost controller. Only of course to the limits of the MAP sensor. Anything that you would like to add feel free. thanks
