SLP MAF question...
say is for '98-'00 will lean you out somewhat. The
'01-'02 is mixture-neutral, going by my car's
lack of LTFT movement.
The MAF may have the air temp sensor on it, but
it comes with a pigtail harness that basically
ignores the IAT and passes only the supplies and
output to the stock F-body harness (and the IAT
portion of the harness is still left on the lid,
as-is).
If you don't want to change your "natural" mixture
and MAF calibration, get the late-years version.
If you think you want to "lean it out for more
power", I'd suggest you know where you stand
before you dollar down. Otherwise you'll be back
here asking "why am I pinging like a sumbitch?".
Or, save your money for something that will give
you some actual performance improvement and keep
the stocker until you have every other bolt-on
and run out of stuff to buy.
