255 MAF? (was blm based tuning)

["Dave Zug" <dzug@delanet.com>]

Question:
Would not the MAF show a flat line at 231 if I wqas maxing it out (AND 231
was the MAX)?  What it shows it a sloping increase in readings that peaks at
231 for a usec then maintains slightly jittery at 228 or so until the R's
climb to 4800+ , then the airflow drops slightly. If I was maxing it out,
I'd thing it would read the MAX value and flatline there, cause the air was
so much greater volume than that. Let me know if I am mistaken.  Of coarse
theres no mention of "a 255 MAF" or a "XXX MAF" in any postings I have seen
(most since the list started).. is this one of those "secret secrets"?  do
you care to elaborate on the concept?  care to point me(us) to a part number
of a '165 compatible 255 MAF?

I have 2 MAFS,  the gutted 1989:  #0 280 213 009   10 055 877  and ungutted
1986: #0 280 213 004   14 094 712
