getting false boost readings from pcm .All sensor's test fine on the input side to the pcm but it doubles the boost reading coming out . this was confirmed by scanning pcm and a manual gauge tee in to the map sensor line. Best place to get new pcm.Would perfer to get diffrent pcm and not have this one flashed

How much different did it run when you put the new pcm on it? Where did you get yours from?
