So my buddy and work colleague recently purchased a 2017 Cayman: 2.0, Agate Grey, PDK. He had H&R Sport Springs installed along with spacers for the front and rear. It looks really good, but it does sit rather low. Vivid Racing is a local tuner shop in the Phoenix valley. The VR Tune is their iteration for an ECU tune for the 718. They used his car for the prototype of the VR Tune. I drove his car before and after the tune. There's definitely a feel of increased power! It's absolutely noticeable almost everywhere in the powerband. Because of the slightly increased boost, you do feel a bit more lag than normal, but then the power comes on stronger than normal as well. In my opinion, it gives the car almost the same amount of pull that you get with a Cayman S, but the power delivery and feel is much more natural in the Cayman S. For the money, it seems to do the trick. I will likely get my car tuned as well, whether I'll be using the VR Tune or not is still up in the air. I'll see as his car put the miles on. In the enclosed link below, that's his car they use in the YouTube video and pics.
