Will stock maf work with 92mm TB?
I recently upgraded to an 85mm GM maf with a larger mesh screen and retuned the car and have no gains to show for it. Stock is fine for at least a mild head/cam car. I would wait until you are getting serious (over 460rwhp) to worry about a MAF.

From what I've heard though, MAF changes are better suited to a dyno tune over a mail tune.
