Will the stock MAF handle up to 500 HP as measured on a engine dyno or a dynojet rear wheel dyno? I'm pretty certain people are talking about RWHP here. Can't find an answer using the Search feature ... can somebody confirm which it is the stock MAF can handle?
722 RWHP, stock maf, Force Inducted of course...This is on an LT1..

Yeah, you can peg out the MAF by 4000RPM and fake
the PE vs RPM from there on out, having a fixed (bogus)
airflow value at least makes it stable Back door speed
density, hold the density, extra cheese.
But most of us should be so lucky to have that (maxed
airflow) problem, and want pleasant street drivability
with as little error added to the system as possible.
There a known-quantity type MAF makes a simple tuning
exercise or none at all.

With the table extended to 511.99 you guys peg the MAF at 450-475?
The question is where is it out of measure; not what did you make. Your MAF did not meter for over 700RWHP. My LSx is blind by 9psi or so, so on a MAF tune it's max fuel from there to peak boost (~15.5-16psi for me).
