Which MAF sensor is sufficient enough for me?
Also, would ported MAF ends also help? I'm the kinda guy who is trying to get every little bit of juice out of my car in upgrades, big or small, and realized I could get a decent gain with this upgrade.

Later switched to Granatelli w/polished red ends.
Will sell it, PM me.

Air passes over the MAF leads. The MAF generates a frequency. The PCM looks that frequency up in a table that corresponds to an airflow value of XXX.XX grams/second. If you change the metering device (by descreening, porting, or swapping for something new) or even the path of airflow (eg an aftermarket lid), you WILL need to re-map the table for the PCM's commanded AFR to equal the actual AFR produced. Plain and simple....
People don't see the numbers unless they have a tuning suite like EFI Live or HPT. That means they're talking out of their asses 90+% of the time. Yes, you can take a stock car, port and polish the MAF, throw on a catback and a lid and get HP gains. Some of that gain is not just the engine breathing better, it's also the AFR leaning out. The PCM is still commanding something rich like an 11.7:1 AFR at WOT. However, the mods throw off the accuracy of the fueling calculations and the car is actually running an AFR in the mid to high 12's. At least, that's been my experience.
A good example...my bolt-ons Z28 (with stock MAF, SSRA, lid, headers, !CATS, and Magnaflow) had a 6.5% error between the commanded and actual AFR at WOT. I had to increase the MAF table to adjust for the changes in the airflow characteristics so that when I told the car (through the PCM) to run a 12.8:1 AFR, it did.

and kept my stock MAF sensor. I didn't feel any significant gain.
