Will I gain additional power, smoothness, AND safety by having my car tuned?
By installing a catless up and down the turbo spools much easier. It is also able to run more boost, and leaner, safely. EM is always a good idea if you are looking to optimize your setup.

Even on a stock car EM is a good idea in my book.
