The GR Corolla and Yaris twins are powered by a 1.6L 3 cylinder turbo direct and port injected engine! That's a mouthful! What we want to do is what these little punch above their weight powerplants have packed under the skin. Can we make more power with tuning - and if so how much?

We walk you thought the tuning and flashing process of the cars (using EcuTek) and I think you'll be impressed with the results. We certainly were!
