This post is complete madness.

Reverse engineering the ECU, communication protocols, flash algorithms, disassembling it to see how it works, finding the look up tables for everything, figuring out how they interact, when they're active, etc. is a much harder job than adjusting fueling, timing, wastegate, and boost settings. WAY harder.

Tuning a car is an order of magnitude easier than hacking an ECU.
