I'm not backing out but I do have a question. One of the early pictures of the new units shows them with an SVT speedometer going to 130 MPH. Another one on another page has it with an SVT speedometer going to 160 MPH. My SVT speedometer goes to 130 MPH. Am I safe to assume I'll have no troubles? While I'm asking questions, will the speedometer and the tach have to be recalibrated? Thanks.
