[Shotimes] 77mm Pro-M MAF quality

[Mark Nunnally]

The machine work on mine is rougher you see on other stuff, but the results
are great.  Adding that and a dynomax catback added 19 FWHP and 14 ft/lbs of
torque on a dynojet (on my 3.2L).

If you do your own tuning it's nice to have a meter that you don't have to
mess around with the MAF curve table.  The flow bench data sheet that came
with mine is almost spot on the factory curve.  Have to wonder how much hp
they can support though (an 850 kg/hr meter) as I'm getting up near 4.4 max
volt on mine at torque peak (at about 216 peak FWHP, about 260ish at the
crank)

I'm quite disappointed wrt to assembly quality and the appearance of the
meter. It's almost like some 10 year old did the machine work on the meter.

rough.  And the sample tube is a joke.  On Pro-M's web site, they make a big
deal out of the sample tube opening also having a venturi shape. Woopeee,
lucky me. Pro-M must have learned that a straight uniformly shaped cylinder
all the way from the sensor element to the opening is a better approach,
cause that's what my meter has.  Maybe Venturi in the sample tube doesn't
make a darn difference.  That is a possibility. But then don't hype it up so
much on the web site.  Shit like that just makes my upset.

> According to Pro-M all the meters they have in stock look as I described
it above.  I'm not sure I believe them.  "Try it out. If it doesn't perform
well, return it.", they told me.  So I have not done that yet.  In the mean
time I'm just curious what other 77mm Pro-M meters look like.
