i HAVE A 2012 287 SSX 8.1 VOLVO My tach on the dash is off about 1000 rpm lower than the tach on the digital read out? I know the digital one must be correct because the rpms as related to mph makes more sense I.e. 3000 at 30mph on the digital when the dial is about 2000 rpms I've heard that there is some kind of adjustment than can be made on the back of the unit? Anyone?
