Heres a new one: How about if, when I change the injectors I just
make the new MAF bypass tube exactly the same ratio change as the
injectors ratio change? I mean stock injectors were 22#, new
injectors are 28# so I add inlet area to the MAF that is 28/22
larger than the original! NO ECM CHANGES! did I hit on something
here? at idle the car would see less airflow than stock , and
provide a reduced inj pulse.. which is correct cause the injectors
are exactly proportionally sized larger. huh.
oh oh.. I just screwed every MAF chip maker out of money.
