Is GMS going to make a 90mm MAF for the L? I've called twice since I got mine and got a different answer both times. First, it was to be out by the end of the year. Then, I was told that the 80mm was it and that it out flowed the stock 90mm. (Would you like that on Visa or MC sir?) Yeah, Riiiiiiiiiight!
I need help guys (and not guys )! Does anyone know the answer?

 

The GMS Maf is the Pro-M MAF. Granetelli bought out Pro-M. The GMS Lightning MAF is the Pro-M Lightning MAF. They are marketed the differently but are the same part. I have not heard of a 90mm GMS or Pro-M in the works. If they are referring to the 80mm part, it does NOT outflow the 90mm Ford. However the 90mm Ford only flows about 4% more, so they are close.

 

I didn't know that GMS and Pro-M were the same. I did know that the 90mm outflows the Pro-m slightly though. Thanks, Sal!

You headed to Rockingham in October?

 

I've had a GMS Pro-M 80mm on my truck forever. It has run flaylessly since I bought it 26,000 miles ago. I guess they flow pretty much the same as the 90mm's so I wouldn't change.

 

I heard they were just going to make the hole larger to fit the bigger boot. But it will remain 80mm. The pro-M has a much smother path for air to travel. On the 90mm you have that arm sticking half way into the meter.
