I found the correct tach wire off the ECU and got it hooked up and I remember reading somewhere that the rpm signal coming from the ECU is around 500 less then what the factory cluster tach reads is this right? I have a shift light with a digital tach in it and it reads around 500 or more depending on the higher RPM's which do I believe? I can't find what I read about a week ago about this so can anyone confirm.
