Our customer Jesse recently put one on his blacked out 991 Turbo that looks stunning with a set of HRE Wheels, exhaust, and carbon fiber Agency Power tips. He has been driving the car around and told us, “The VRtuning box virtually eliminated the thing I hated most about the 991TT…the throttle lag. Now the car is violently fast yet power delivery is nice and smooth. The power is there when you want it…and docile when you don’t. The product works better than advertised and I wish I did it sooner.” Order your VR Tuned ECU Tuning Box for the 991 Turbo Here. Leave a Reply Cancel ReplyYou must be logged in to post a comment.
