I prefer to answer questions here to help all who may have the same question in the future.
Although I am too busy at the moment to make any promises.
The truth is that there are better people here to answer just about any question - I'm no guru, just a tinkerer myself.

Non A maf modification
I was reading one of your older posts on NonA maf mods.
WOndering if you had any more insight as to your mini v-stack for the modified sampling tube?
Is there any other options? Can the tube be resized with an o-ring?
thanks.
Mike.

If you've got the money/can afford it try to get the 078/471A housing/sensor...
if at all possible. Reason being you can only get 71/72% of the airflow thru the non-A housing due to the rather large, restrictive profile of the sampling head assembly that must remain in the air path to form the metering orifice over the MAF sensor sampling wires in the non-A MAF housing. Important because the MAF, is "the" biggest restriction in the intake system on a 12V and a dramatically bigger improvement when opened up than ANY other component in the intake system including throttle body which is a distant 2nd place no matter who makes it!
If you only do one single mod on your cars' induction system, make it the MAF! And if you're gonna be a dog MAF-wise, why be a Chihuahua!?!

Sorry, but all 078/471 non-A MAF pictures are gone but I can describe the process...
as I'm the one who wrote the post you linked and I specifically remember the pic I took to accompany it.
Basically what you want to do is cut the column that supports the sampling orifice head off flush with the underside of the sampling head using a hack saw blade with a single handle or wrapped with a paper towel so you can hold it in your hand while sawing. Then cut the other end of the column off where it connects to the opposite side of the MAF internal wall.
Then sand smooth or Dremel the areas you cut smooth and flush with the sampling head under-side and MAF wall at opposite side where column was connected before being sawed off. Essentially cut the vertical support column off and sand smooth all areas that sawing made rough.
In the 078/471A MAF housing the ENTIRE column WITH sensor metering orifice head can be cut out and sanded smooth which reults in ~30% increased flow over the non-A housing.
