Jax951

I've been looking at all the MAF kits out there. They're all expensive, and naturally we all want the best value for our money. I've seen MAF's made by:
Autothority
Huntley Racing
Lindsey Racing
SpeedForce Racing
I'm sure there are a few others (feel free to name other brands).

Has anyone done any testing on all the different models? Are all MAF's the same (disregarding price)?

Are they really worth it?

I already have Autothority chips on my car, and noticed that the Autothority MAF also comes with chips - are these the same as their regular "performance enhancing" chips? How come no-one else has chips for sale as part of their kit?

Are chips even necessary when you have a MAF? Could they possibly even detract from performance?

And my final question: Do all high HP 951's have MAF's installed - i.e. is it a pretty standard upgrade for people serious about HP?

Thanks guys...
