Mike,
I would agree with the others, that although you may not feel a seat of the pants performance gain vs a properly working stock MAF.......you will gain 1) reliabiltiy (as these LT-1/LS-1/85mm Z-06 MAF's don't crap out on you), 2) you now have tons of adjustability over a wide range of rpm's and can add or subtract fuel, timing and have wide band compatibility), 3)plenty of availability of these MAFs. 4) with the extender extreme chip it fools your system by allowing your ECM to see 3 x the air flow numbers of your stock MAF...ie 765 gram per second vs the stock GM MAF of 255 grams per second at WOT.
Did I say better tunability!
Although I don't have any way of measuring it, I would have to say that I believe my car idles and runs smoother than it did when I had the stock set up on it.
After your initial PURCHA$E of these items, you don't have to keep throwing away money again and again on stock maf's that crap out or don't work properly.
All I can say is that I'm very pleased with my set up and would highly recommend it to anyone who is sitting on the fence.
