Hello to all...im driving the new saga lmst...last week ive change the cam pulley to an adjustable one...theres marking A and R...according to the shop i bought, for pick up it should be at A, but i gain lots of lagging at A, its better at R. My prob ez dat the pick-up of my car is not that powerful compared to previous. If anyone could provide me sum info bout the setting and some product knowledge on adjustable cam pulley, i would be gladfull (no changes on the cam)!!! thanks.
