[s-cars] MAF upgrade?

[MLP]

Phil -

I've hesitated to say anything at all about this, but.....

Alternatives exist, but are they better?  That's very much a YMMV issue, and
IMO for all stock to RS2 applications, probably not.  Past RS2, is there a
better MAF?  I'd give that very qualified maybe, and you have to remember,
the MAF is just one component of a fairly intricately intertwined system.
Any measurements that could / would "quantify" the benefits (other than Rod
H finally reportedly perhaps finally drawing a breath deep enough to suck
the hot wires off a stock unit his through his intake manifold) have yet to
be made or taken.  At the time Rod was pretty bummed.  I told him he ought
to look at the bright side.  By my guess, I told him it could be seen as a
sign, and he could claim it as some sign of proof he'd finally passed the
400 to 450+ bhp mark :-).

In the course of chasing some of the above, there is another question /
possibility that can be asked about the origins of a MAF cause stumble.
What thoughts are there re feed back from too much pressure in the intake
track causing "blow back" via the BPV that confuses the MAF?  Any takers?

I can tell you that under highway cruise conditions, say a steady 55 - 70
mph, light throttle application with a basically stock car (i.e. K24), one
can be running and holding 5"+ of (I believe the Autometer gauge is
calibrated in Hg) vacuum in the intake manifold, but have the turbo pushing
4+ psi of boost at, in and through the intercooler up to the throttle body.

BTW, for those who enjoy anagrams, I see that if you carefully rearrange the
last part, SDT, you will come up with a STD

Apparently the stumble I've been chasing for quite some time is a bad MAF
meter - it puts out bad values.  Yes, it's been cleaned.  Has a better
replacement been found for the stock Bosch unit (best price so far $405)?

TIA,
