That said, I have had an excellent experience with the MAF update on my 964 3.6. The motor starts better, idles better, and part throttle acceleration is transformed. I can't speak about the 3.2 Carrera performance, but I assume it would be similar.

I never expected a "magical source of horsepower that Porsche missed out on" but wanted to eliminate problems with tracking wear of the AFM contacts on the resistive strip in the unit (a problem we all know happens on these 30+ year old units). The performance improvements I experienced were a bonus. As far as the AFM being just as good as a MAF, PAG sure thought it was an improvement when they when they UPGRADED the 993 to a MAF instead of the 964 AFM!

I will agree, there were some less then steller attempts early on in replacing the AFM with a MAF (AutoAuthority and others), but that was years ago and over the years some folks have improved and upgraded with a new approach.
Do a little searching on Scarcellers excellent MAF upgrade solution and the glowing reports from the folks who have used it.
In my world, first person experience trumps Googleing and posting a lot of quotes from other people from who knows how long ago.
Kinda like "the proof of the pudding is in the eating"
Just my $.02
