Pro M manufactures the units to Granatelli specs, they just rebrand them. As for your whistling accufab - what size tb and what intake? When I had my 70mm accufab on my stock intake (63mm port) it whistled at part throttle. When I put the performer on (70mm port) it stopped.

That may be your whistle. If you plan on keeping the stock intake you may want to open it to a 65mm gasket.
And I'm happy with my pro m bullet, only issue was some difficulty getting the cold air kit on around it (it's longer than the stock meter housing). I'm not sure what the difference is between the pro m/granatelli specs, just make sure you get one calibrated for your injectors and intake tract (stock/conical/cold air) and you should be fine.
First things first,,I need a maf... Is the 77mm shorty any longer or shorter then the Bullet??jb89coupe said:
GET a Pro-M...I would go with the 80mm since it is cheaper....than the 77mm...it is plastic, however, and not aluminum like the 77mm...look on eBay for best deals on both the 77mm and 80mm...I have 2 77mm and I have no complaints...they make them both in a shorty style and a regular style...both take a conicle filter
I have a Dense Air Charger fenderwell unit!! I guess that means I have to go with a bullet,,,Ill call and ask I guess.Highbredcloud said:

Granatelli just wants to make a profit.. the more hands a product passes through the more the cost goes up. I'd just get a pro m personally. Summit/Jegs may not carry them but a ton of other places do. I got mine from Mustangs Unlimited, I deal with them all the time and their service is great.
Edit: By the way the "difficulty" I mentioned in getting the bullet to fit my cold air kit was just a minor issue - it's on there fine. I've since taken it off/put it back on probably a half dozen times, it's just a bit of a pain.
I picked up a 75mm pro m for 169.00 
Those 77 and 80mm pro m's are extremely expensive!!! One guy told me they were for blower applications.

Demolet automotive,,he makes the dense air charger cai.,,He usaully sells them for 179,,but being Im a past customer he let it go for 169!! And he said he will set it up for his system(I have his CAI) how Im not sure.jb89coupe said:
That's a good price. I had a densecharger for a while but traded it for a mac cai. Everything else under my hood is polished aluminum/chrome, so the black plastic kinda looked out of place. fwiw I noticed no performance differences between the two systems.
Really,,,He said you can notice a difference in the summer when its hot.I cant tell because its the only one I had besides stock.BUT I do notice a difference in the real, real cold weather,my stang runs like a raped apejb89coupe said:
