Warranty friendly mods for now-
Was worth getting in my opinion. Car runs much smoother through lower gears as well as delivering the power. Is it something dramatic the butt dyno will feel? Not so much, but still worth the buy IMO.
In my experience with tuning hardware and software (though most my experience is with Hondas). It is the gift that keeps on giving. As you modify/upgrade your car you can take it in get it tuned for specifically what you have and ensure that your engine is running in a safe place or at least lower your chances of blowing the engine up.
I also like to remind everyone that a dyno is like a torque wrench it's there to make sure things are "in spec" dyno numbers are actually pretty useless the power curve and the gains the car makes under the curve are the more important. Really the only way to actually know if you car is faster is to take it to a track and see if you, as a drive, can beat your last time. Just my 2 cents
