Mass Air Flow Question
thats funny, cause new GM vehicles use a Card style MAF...from the factory. The Card MAF is not the issue.... its the Tuner not knowing how to make it work... you cant just adjust the MAF table alone when you switch from a Wire MAF to a card MAF... theres an entire page of other variables that you have to change.
I'm aware they use them from the factory. Just sharing what I've learned through multiple discussions.
I'm fairly certain Geoff knows what the hell he's doing. I'm simply stating he doesn't like them.

Short distance between filter and throttle body when installed in a f-body. It's such a short run that the straightener will stabilize the flow through the sensor and give you a much better idle. Too many guys are all about wot, that's crap to me. 90% of the time your car is either at idle or low rpm and the straightener in our cars makes things a hell of a lot better. Scan a LS with the card style in one of our cars and you'll see that it will jump between 3-4 cells, then put a straightener in and you'll see it locks into just two. The tighter you can keep it the better the idle quality. At low speed you will also see a huge improvement in the reported hz from the sensor and is a lot more stable. Stable flow measure equals a smooth, consistent ride... it makes a huge difference

Couple of picks of what Im getting at here. Here is a before and after of a 100mm MAF without and with the straightener in place. This is a test that the boys did on HP site a while back and has been used by many,many guys to fix the problem.
I see. Didn't know they were larger. Strange how the various threads where Saxon is mentioned, it's not stated that the opening are larger. Could I have missed it?
Thanks for the info. I've just fitted a Saxon honeycomb into my new MAF tube.

I believe that thread is called "Replacement Airflow Straighteners"
The Saxon screen has larger diameter holes and they're three times as thick.
My 04 Corvette doesn't have a screen, but rest assured ones on the way to replace what isn't there.
