Everyone has a different opinion on the Power FC, whether to get AFM's or the D-Jetro version. I bit the bullet yesterday and order the D-Jetro, which has ended up costing me less than a normal PFC and 2 AFM's. I like the idea of MAP's over MAF's because of the stalling and messing with bov's (as said in below posts)
If you'd like to be turned away from the D-Jetro, read this

^^but then the second last post gives the D-Jetro some hope, plus all of those guys know what they are talking about
