We have just released our Build 0065 which features the new read and write process for the SDI4 Siemens ECU found in the Porsche Cayenne V6, V8, and Turbo models.  The SDI4 tuning has been around for a while but the ability to get past the security key was a small hurdle.  However it is now in place and rockin away!  So if you want to boost up that horsepower in your Porsche SUV, get VR Tuned!
