Best Tuning Option

Hi all,

New to the forum. Just bought a black 2013 ATS 2.0T last week and looking to get started right away on performance upgrades.

I am just starting my research, but in regards to the tuning options available out there. Which do you all have and recommend?

So far I've looked into ZZPerformance, Diablo, and the KPE tunes the most.

Which is the better bang for buck?

Any help is appreciated. It looked like ZZPerformance was cheapest, but cheaper isn't always better.
