if you are talking about calibrated MAFs, I would sudgest doing that as the last mod. IMO it will only provide a noticeable gain after other mods are done.
My .02 cents...
I only plan on getting one after I change everything I want to change enginewise.

Plus, someone correct me if I'm mistaken, but I thought the ideal MAF sizes were 73 and 75mm. Always thought 80 was too big...

thanks, i just posted this, because i heard that 80mm MAF doesn't need to be programmed no matter what mods you have or even if you add a new, but i heard also the 75mm gives more gain,the only problem with this one, it's needs special calibration

I still say that a calibrated MAF would be done as one of the last things (except for a chip). If you want to get it now, I would at least optimize the intake. Save up and get SVT intake manifold and TB, then a CAI... why not just getting an exhaust??? from your sig it seems like you dont have one.

One question, isnt the 80mm MAF the one from a mustang? If so, didn't it actually produce a loss? I remember something like that on the boards way back in a day...

yeah,i heard the 80mm is too big, but i just trying to get some cheap hp, i just bought the shop shop Y pipe with no cat, and i'll gut the precats also at the same time, i just don't 400 dollars to spend in exhaust for now, but i will.

The Y will free up some flow, but the stock rear muffler will still be a little bit of a restriction. For like $40 you can get Mineky to swap out your rear muffler with a straight pipe, and then youll almost have an aftermarket system :shrug:

tell the truth i didnt really feel a difference after my duals

I recommend you read this post. MAF upgrades are a waste of money unless you're in the top 5% of mods to your Cougar.
