Hi all my 2010 mazda 3 2.2D (150) has serious lack of power low down the rev range until it hits approx 2500rpm. It's almost like there is no turbo boost until 2500 rpm. I've been underneath today and pulled off the vacuum hose and there is no vacuum getting to the wastegate actuator, same as the the little actuator thing on the throttle body doesnt budge at all when revved. I can't seem to find much info on this engine as I do not have a manual, but where the vacuum pump would usually be ( back right corner of rocker cover running off cam ) appears to be the high pressure pump on mine. Does anyone know where the vacuum pump is on this?
