for the $, I say pullies and tune.

 

What's MAM should I get that would work with my AEM cai and where is the best price?
I was looking at the Pro M is that the best one? Also is 85mm the right one?

 

I wouldn't spend the $ on a MAF yet. Ford has a pretty good stock MAF for the mods you have.

 

What pullies do you guys like? Is there a 85mm MAM or is it only 80mm for the 2001 GT?

 

I think a 350 Predator tuner is good too. Calibrates the speedo for the new gears, eliminates the need for a timing adjuster and can also act as a po' mans shift kit for autos(kind of). Plus, it has a ton of other features you can play with to tune your car. For 350 new, I think it is a good deal. Oh ya, no busted knuckles or labor costs for installation.
