MAF test/upgrade
Can you take your MAF somewhere and have it tested? I'm not talking about tapping the MAF during idle.
Also, is there an upgrade, or has anyone ever tried a MAF upgrade to a larger size?

Go to http://www.sunpro.com , click on the garage sale link, click on test and tune, and buy their sensor testor for cheap; it tests MAF sensors.
Either that or any shop with a computer can show what the MAF is reading.
What's wrong with your MAF?

Nothing's wrong with the MAF. I was just curious for future reference. Thanks Tom.

Like hell I can't. You wanna say that to my face? Just kidding.
The reason I asked is because I found this website selling MAFs for trucks (I think GM trucks) that were upgrades from stock (larger of course).
I was thinking if you're loaded, you can pull apart the one for our car and mount it in a larger tube.

is it worth it? how about 'no'?
the maf/ecu are calibrated to that size tube. Increase the tube, the ecu will interpret the maf's signal wrong.
You'd need major reprogramming.

I'm not disagreeing with you Doward, but I can't see why it would matter what the size of the tube is, unless the board inside needs to be in a certain proportion to the size of the tube.

Actually, it's the flow of air through the tube that's important.
it's 5:30 am, so I'm not really up to the math part of it, but in a nutshell -
Smaller pipe = higher velocity for the same flow
Bigger pipe = lower velocity for the same amount of flow
WIth a bigger pipe, the MAF reads it as a slower velocity (the air flow) and hence, the ecu reads it as less air.
The key would be to go from a 3" to whatever size flows exactly half the velocity for a given air mass (or double the air mass at a given velocity) and then recalibrate the ecu accordingly. But as far as I know, the MAF scalar tables are still a huge item of mystery....

Well, I guess it would have helped if I knew how the MAF worked. Now that you tell me it works on velocity it makes sense. I should have known it had something to do with Bernoulli's Principle.
