I've done my pump gas pro tune with Dzenno@PTF. It was a blast, a true learning experience and I enjoyed every moment of it as I finally learned some technical tidbits about the car I drive and enjoy daily. I have not had a chance to dyno yet but the car is way more response after the pro tune and feel stronger throughout the RPM. OTS maps were also amazing from stock but this took it up noticeably further. Hopefully some local guys will organize a dyno day soon and I'll be able to hop on to see my results as well and share here with the rest.
