Hey man i don't know who told you that about a PFC, but if it has a standard map they come with then you just plug the PFC into where the old computer was....umm labour....not really existant...how do i know this well i have one. and you use standard AFM as well. If you want a different AFM then you need to get it tuned for it. PFC is best bang for bucks along side getting you standard ECU chipped and tuned.
Seriously PFC, see you can find one. 2nd hand they usually go for about $1200, with a hand controller.
EDIT: Chipping standard ECU is good. you don't have to worry about wiring and new farken ECU, was going to be my choice if i didnt find a PFC to use. Chipped standard ECU will give you about the same about of tuned abililty as a PFC.
