did you miss my post above yours?
why you would ever want to put that thing in an N/A car is beyond me.
seriously trust me on this, a stock maf is good for ANY N/A 3400.
the ONLY time you really should even consider swapping a MAF for a larger one is when your boosted and boosting pretty good, over 8 psi would be the minimum i would even consider swapping it out.
like i said before, ive got a turbo on my 3400 and i boost at 12 psi and i am not maxing out the stock MAF yet. the stock maf will handle gobs of flow. at 12 psi the maf freq is only 11,200 mhz. the stock maf goes to 11,500 just like every other maf out there.
you put in a bigger maf without changing your maf tables and your gonna run VERY rich or VERY lean.
I will show you what a stock 3400 maf and the 75mm Tahoe (LQ4) maf table looks like, and you will see its not even close.
you should look into the TB before you ever think about the MAF.
