Can you share what your minor issue was?? Just so I can keep an eye out just in case. Thanks!!I've put over 5000 miles on my truck since SKT tune and only had minor issues that they resolved immediately. None of these ever affected the performance of the truck. I pull a 4600 lb Toyhauler so I'm really happy with the towing performance and fuel mileage. Once the software is on the laptop it's a simple procedure to download updated tunes even while on the road. All you need is an internet connection.
