I was thinking the same thing Slow ride.
The MAF is the easiest thing to tune comparatively. That's IMO of course but it really only took 2-3 pulls and was done. Should note that screening the MAF helps a ton with the stability of the sensor.

I don't remember the density I got but it's pretty low. It made the MAF much more stable and my AFR is rock solid 12.8 all the way to redline.
I just sanded the inside of the tube to score it and used JB Weld. It's been holding for over two years now with no signs of wear.

I would think getting part throttle flow dialed would take a little time.
I find it funny someplace is selling the honeycomb when so many swear it is purely bad. I am NOT saying the honeycomb is bad, I understand what it does and believe it will improve reading stability.

The thing about the MAF is that airflow is simple. Engine load doesn't matter. Just make sure you hit every cell in table(only one row) and you'll be pretty much gtg. WOT will take a little tweaking to get the AFR dead on but it's way easier than the VE table.
As long as the screen isn't providing a restriction I can see no downside. I get 99-101kpa all the way to redline.

Yeah, but if you have different injectors it's going to take a lot longer.
I had a custom 85mm at one point. I REALLY liked it bc it put the reader portion of the card MAF directly in the middle. I've noticed with the TSP and Lingenfelter's their off a bit to the mounting side.
GMPP aluminum card MAF bung: $11 (weld it to pipe below)
eBay 6" long piece of aluminum 4" ID pipe: $15 shipped
eBay LS3/7 Card MAF (Cobalt as well, and cheaper) : $40 shipped.
My goal now is to customize my SLP lid and make a 92mm MAF. Geoff wants me to get my 42# injectors installed and tuned with the stock MAF first though. We'll go from there.
One thing he has told me and warned me about is how erratic and sensitive the card MAF's can be. Even changing the position of a fan while on the dyno can really throw it off.

I wonder if a screen installed before the card MAF could steady the readings?
Few folks understand how the MAF works.
I found that mounting a cone filter with the inverted cone in the end to the MAF read funky even with a screen.
The smoother the airflow is coming into the MAF the more steadily it will read.

Pretty good info in here. Where to buy the honycomb.

Anyone tried the spectre pipe with the FTP lid?

Yeah, when I was debating whether or not to do the LS7 cartridge MAF, I found that discussion on HPTuners. Those honeycomb screens straighten and smooth out the airflow, which seems to correct the issue. Otherwise, those MAFs can run a bit crazy if the air is just hitting the screen all ***** nilly.

If anyone is interested, I've got a complete kit for sale. Brand new. I've decided on a carb style and SD tune.
