The MAF needs to be tuned for. I believe the MAF is 4 inches and the stock TB is 3 inch or so, so that means you would need a custom coupler to make it work.

I think FTP 104 is made specifically for the 100 MAFs and then would need a reduction coupler to go to a 90mm TB/intake. It should be a direct fit for a Fast 102 though.
My FTP lid fits like crap, I brought when i had a shop do heaeders and a stall, the FTP lettering is rubbed off on to the hood, i don't even lift my hood due to how bad it fits. I should have brought to the installer as soon as I seen the prob but thier out of biz and I have no receipt.
I have it bungee corded and duct taped to seal it lol. And I hea about bad fitment from all and for what little if any it did for me perforamnace wise I would have stuck with stock.
Planning on on a H\C in the future so I guess gonna have to buy new lid assembly and upgrade MAF. But yes waste of $180 0r whatever it was.

Unless you got a big cube motor those huge lids are def killing the velocity of the incoming air...
Anyway I have a SLP lid and the top of it rubs on my hood too...it's pretty much unavoidable

I don't know about all that. All you're doing is supplying the manifold with as much air as it needs. The runners are going to determine the velocity, not the size of the lid or anything else.
People are putting on 102mm TB's and intakes and gaining power. I think you're wrong.
They might be gaining power but I will guarantee that the extra power is high in the rev range...which verifies what I'm saying bc you have to have more rpms to get the air velocity to the point where it is Efficient enough to make the extra power...putting a huge airline/Maf/tb/intake on a stock cube ls1 might gain hp up high but it comes at a cost of low end torque...look up some dyno charts....changing the size of ANY component of the air intake system will effect air velocity, not just the manifold

^^^ I agree and I think its rediculous the prices people are asking for fast 90/92 units you might as well buy a new 102 unit and people were saying the same thing about 1 7/8 headers and we all no how that turned out so I only take so much from the internet these day, but you no im just sayin!!!

Fits great on the shelf in the tool room 
I don't agree with any of your airflow logic and my SLP lid does not rub. Sounds like it's your car and not the lids.
Nope, try again.
I think it would.
