Pro-M Mafs
Pro-M Mafs Has anyone tried these yet or are we still recommending the stocker. Do you think they really calibrate them correctly or is this just a marketing hype? Any results or gains would be awesome. 
According to a Granatelli marketing chart I saw
the Pro-M is richer than stock and the Granatelli
"just a little" leaner. Likely that you could adjust
the Pro-M yourself, then, but probably not what
you were looking for.
I'd say until you find a supplier who will give you a
guaranteed frequency/flow data set that you can
tune to, or guarantee within 1-2% of stock cal across
the entire band, it's just more trouble than it's worth.
Unless you like that kind of thing and want to make a
hobby of it.

No, Z06 cal is almost identical to truck MAF cal
(differences are almost certainly due to screen
and intake tract). On an F-body these MAFs
will put you 15-25% rich and this is not good.
The plus is that you can modify them to be
pretty good fits to the F-body, cheap. But out-
of-the-box, not right. The engine is structurally
the same on a 'Vette but its PCM is programmed
for the proper MAF freq/flow characteristic.
If you were gonna get tuned anyway, you could
just use the Z06 or truck tables and end up in
good shape.

Verdad Gallardo Ha, sounded too good to be true. Thanks guys. You're right about the Z06 mafs for us. I bought a PACE one with a 85mm TSP lid to match and I threw an SES! I reset the computer and sure throttle response was better, but it didn't pull like the stocker. I have to sell it now. Ha.

If you have any kind of logging / real time display tool you
can tune it in yourself, if you want.
