Warranty P other comment is interesting as well. A flashed ECU seems to be a voided warranty now from what people are saying. I've been told flash tune sales have slowed lately due to this.

This statement is not entirely true. Most of those cars you are referring to run a JB4 to be able to integrate meth injection or E85 to be able to make the most use out of their upgraded turbos. Not to mention that a lot of them run a back-end flash as well.
Ran against an M4 with JB4 and full bolt-ons (DPs, intake, and straight-pipes), pulled a couple of car lengths against him with my M3 running on an OTS map and DPs only.
