Correct -the only V-6 Berettas to have a MAF (stock, at least 8) ) were the '96 3100s, which DID have both MAP and MAF sensors, and the '87/'88 2.8MPFI cars, but those had a factory service update (assuming the owner ever got the car in for the recall) to convert to speed-density (MAP), and use the MAF only for its' IAT function. Unfortunately, that MAF was still a restriction and source of power-loss. But either way, it wasn't used on the 3.1 engines... I scanned around a little on this thread, and didn't see the year of the car in question though, but I am pretty sure he has an older 3.1 MPFI car...

1989 Super Charged 3800 Series II (First)Six-Speed Conversion GTU
1990 Turbo 3.4 5-Speed T-Type
1990 4.0L 4-Cam 32-Valve V-8 5-Speed Indy GTi (Project)
1990 Stock(!) 3.1 MPFI Auto Indy
1995 Z-26
1995 3.4 DOHC Turbo 5-Speed Z-26

Hehe yeah my beretta is a 91 :)
And about mpg, i already noticed how much better mpg i get :) just repaired my tripmeter in my cluster so i can see how much this improved my mpg.
Im going to connect my laptop to the ecm and check the o2 voltage and all. Have to reset the needles on the tach anyways.
