Sct-x4 adjustments...

[Dominant1]

Can anyone take me through the steps of adjusting my tire sizes now that I've added my dr's which are bigger in size on my Sct-x4. The Car has a custom tune on it now!

Modify the asbuilts or using the Whipple/Ford flare tool is the only way to correct the speedo.

Time to purchase the Whipple flare tool. SCT isn't going to do it.
