Hey all,

I have a 1998 GMC Yukon. Does anyone know what RPM the "Power Mode" switches on in the computer? I don't know the specific term for "Power Mode", but does anyone know what RPM the engine starts dumping fuel?

It won't dump fuel in the sense of air/fuel ratio unless your at WOT, otherwise the O2 sensors and PCM will adjust the tuning to prevent the "fuel dump" you speak of.

There is no "Power Mode" like a VTEC yo!!! LOL
