Since the tech said it would take all of 30 seconds, I just went ahead and had my Dinantronics Sport installed today.
Initial butt-dyno feedback is quite noticeable. To keep me honest, I had the tech sitting in the passenger seat changing modes (Sport, Sport +, Race, and Valet-lol) in no particular order without telling me so I could get a legit perspective on the change. Our first impression was the additional 3-4psi of boost was definitely apparent, but it also seems to hold it longer. We both agreed that overall it pulls stronger than stock. Not FBO-level stronger, but definitely stronger. Like, tingling-in-the-pants during acceleration stronger
I am looking forward to some real dyno numbers to share but in the mean time I'm quite happy with the change, especially for the price.
