My tach is 300 rpm off at idle and about 1200 off at Redline. What could be causing this? I have been having this problem for a couple months now. It is consistent and hasn't changed at all over time. I did a total rebuild on the car and everything seems to run fine, except for a few idle sputters here and there. I am comparing the info to the RPM in DSMlink, which I have been emphatically told is correct. Please help, it is hard to drive this thing at WOT while looking at the tach and doing addition, or trying to watch my laptop log.
