Hello all,

I have a'96 LS/Vtec teg with a GSR gauge cluster along with a Apexi V-AFC vtec controller. I noticed that the RPM is off about 1k between the cluster & the Vtec controller...When the cluster is showing 3k RPM the controller is showing 2k...Which of the two is displaying an accurate reading? I am assuming the Vtec controller is...Just wanted to get the right answers from you more experienced members out there....Thanks in advance....
