should i upgrade to a better mass air sensor?

 

I have a GMS Mass Air thats been on the car for around 8 years. It gave me a solid tenth and a half at the track with my combo. Its worked out well for me so far, but it was $350 when I got it. There will be alot of opinions about these aftermarket units, but hp is hp...It got me in the 11s...When I got mine GMS was the only company making them...I'm sure there are others and even some home ported jobs out there now...

I would do searches on here about a aftermarket MAF. But if you want to buy mine, I have a Granatelli MAF...its about two years old and it works fine. Not sure how much to sell it for..so make me an offer.
