Need to?
Only if you want the speedo to be dead on, but then of course it will be off again when you put the stockers back on.
If you have a tune on a SCT tuner it is a simple change, otherwise it isn't an easy change.

Here's a Q about the SCT: can an SCT be borrowed and used solely to change the diff gear cal? I ask b/c a friend has one for his Lightning and he'd be willing to loan it to me but doesn't want to lose his stock tune, which presumably is stored within his SCT.
In other words, does the SCT become more or less dedicated to a particular car once its been used to download a modified tune to that car?

So yes it is dedicated to one vehicle.
