Plenty of answers if you cared to seatch.

I've never seen a 3-wire 85mm MAF, other than
maybe the Granatelli (don't go there). No Delphi
ones.

Delphi 85mm MAFs all use the same body, there have
been a couple of P/Ns for the screened ("truck") type
over the years. Every vehicle seems to have a very
slight difference in what's in the PCM even if they used
the same hardware P/N.

if you get it tuned then it wont really matter what was on it, although my tuner asked me to pick up a truck version due to the tables already installed are easier to tune.

if you get it from an LS6 vette then all you have to do is have the right size injectors and no tune is required. they have the 28# injectors pre-tuned into them

usually the Vette ones dont have a screen if it was from a Z06 from what i understand. otherwise you would actually have to look at the tables through EFI live to know.

Not true at all. MAF table has to be updated. Air
mass matters to more than fueling, especially on
automatics.
