They do work. :)
The O2 sensors will pick up the changes but once you are in Open-Loop, the
O2 sensors are ignored by the PCM. When you're cruising on the highway
you're in Closed Loop. Once you decide to pass someone, need to push the
go-pedal slightly harder (hill), or are accelerating from a stop, you're in
Open-Loop mode.

Subject: DML: IAT Adjusters?
Do the IAT adjusters really work? Read all the literature and sounds
logical. If by "fooling" the ECM why doesn't the O2 sensor pick up on the
rich condition and correct. Are the only advantages at wide open throttle?
