The Factory FI-ed engine PCM already has in it; options for Boost Controller / PSI based enrichment, boost cut, fuel cut etc. As such an option like the PFC for the FD; or a Flash Tuner is available as a plug and play solution. In the case of a non-FI-ed car that was FI-ed - those sensors and therefore the tuning options do not exist. Make better sense?
I will definitely add a MAF vs MAP section. Good Call.
