    Just wondering if there is anything changes in the EGR flow when driving in Power Mode. In fact, dont know anything, it might be a silly question/idea. Maybe it reduces or stops the recirculation of exhaust fumes, and it might be good for dirty Egr ones, so it pollutes more but gets less or no air from EGR? When I cleaned the intake, I guess, some of the fumes from EGR routed to the intake thru the EGR pipe. Nowadays, using power mode and it accelerates better and seems like no effect on mpg and maybe a little bit better. I know it increases the responsiveness of the throttle and its curve.

    AFAIK EGR circuit is closed at low and high throttle.
    Power mode just put some more responsiveness in your throttle pedal.

    "Power mode" has no effect on anything related to the engine, except to make depressing the accelerator pedal part-way have the same effect as depressing it farther in other modes.
