So if you want to break in your clutch for 500 miles then you should drive until your odometer shows that you went 625 miles (500 x 1.25). You can do the same for your speed. When you are driving divide your speed by 5 and then multiply by 4. That will give you the correct speed and mileage until you get a Speedcal or whatever. So when you show 75 MPH you are actually doing 60MPH.

If you have access to a ohm meter or be careful with this one splice, it is an easy install. The directions are very clear once you begin the job.
YallarStang said:Let me try to ask this question correctly: Would it be possible to "tell" the SpeedCal that you are running 4.30's or 4.56's when you actually have 4.10's? Would this slow down your odometer? I know there are legal issues here, but I was just thinking of the hypothetical possibilities.
downsouthman1 said:Scary. I will surely disconnect mine. But does a speedcal fix the odometer issue as well? I wanna say it does, but does it really? & man does my Tri-Ax allow the gear whine to come right through. I kinda like. Can't wait till Monday when my C&L Intake Plenum & Accufab 75mm TB combo arrives.
