Milwaukee Impact wrench- possibility to mod?

Hi guys,

I’ve decided to take the plunge and invest into cordless tools over air due to the convenience and power they now offer.

I’m looking at getting a 1/2” and 3/8” compact impact wrench both Milwaukee

The 1/2” is a beast and has massive power but Mode 1 can do with a bit more power. It would be ok if it was my only tool but I wondered if a mod to the internal circuitry would allow adjustment.

Anyone have any experience with this? I can pull it apart next week to take a look at the internals.
