Installed the NOS nozzle AFTER the MAF and did a testrun where our WI controller not only controlled when WI was on but also was the trigger for NOS coming on.

This test proved 2 cyberspace myths are FALSE

1. NOS must be injected BEFORE the MAF
2. You cannot run NOS with WI also on.

Both are total bull and in this configuration function just fine.

This really tells you vendors who sell NOS for nice fat profits know crap about how NOS functions and its effects to the engine when PCM is properly custom tuned

Here is the scanner data and as seen IAT (intake are temp) dropped from 80 to 45 degrees in a 80 degree weather and fuel trims when at part throttle around +/- 2 % and at WOT were at zero.



This shows that there is far more negatives when NOS is sprayed through a MAF and also the dangers to damage to the MAF
