[QUOTE="TARM, post: 1423631, member: 578"] My guess is IPR valve. Maybe switching to the syn broke loose some deposits as they tend to have more souring detergent effects and its gotten in and fouled the IPR. A failed IDM should show up in a comp test etc I would think and not sure how it would effect IPR values with duty cycle staying in spec. Why not swap your friends IPR in and see how it does.
