could always use a leaf blower?
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.

aircompressor up the tube worked fine for me, though i was using a scope to test not on a PCM but should be no different.

Re: Different Genuine GM MAF's
What problem are you trying to solve? If you can change the injector rate, would you not be better off changing the maf tables to keep everything calibrated properly?

Re: Different Genuine GM MAF's
When you set up the calibration correctly, you'll hit the limits in the code and theres extended bins for if you hit those that'll handle it properly. Fudging the injector rate and having a misconfigured maf is a pretty ugly hack, I wouldnt be recommending to do it. Sure if you reconfigured everything you might be able to get results, but I dont see why it'd be worth doing that when you dont have to. I know your just throwing around ideas but Im posting this here so people considering maf upgrades dont get the wrong idea about how to tune them.

Re: Different Genuine GM MAF's
not sure if I get the point of it either, but the HZ limit of the maf applies no matter what you fudge the injector rate to be. all you are gaining is faking a little more range on the airflow variables, which could be handy, except now the custom bins have extended the variables, fudging this stuff becomes pointless...

Re: Different Genuine GM MAF's
i think what getrag's getting at is the stock maf vs gen3 maf is about 200hz at the same flow rate, so dropping the maf tables down will then fix the fueling difference.
I think the Gen3 is identical hardware wise to the stock v6 maf, they just made it larger and offset the output by about 200hz to gain slightly more metered flow.
LS7 run card maf, havn't tested one yet but reported to run 15/16k hz, LS6 maf what we use now will do 14's
