As long as you don’t exceed 120% of the original air volume flowing over the MAF, the DME can adapt, no remapping necessary.

A rudimentary volume calculation can be achieved by using the diameter of the original MAF tube vs new and inputting the numbers into the formula for area of a circle. It’s not perfect, but will give you a rough idea. You can then check your fuel ratio to confirm whether or not it has adapted.
