2017 Silverado 6.2 -8 spd auto. We installed longtubes and an F1A Procharger. Truck is tuned and our client has been enjoying for a couple months now. Only real issue I have is that ever since the first time i flashed my first tune into it I get a "reduced engine power " message on the dash. The truck runs and drives fine, no codes in the ECM or anywhere else i scan the truck. I have tried a number of things including flashing back to stock adn the message always appears when you start the truck. It's more of annoyance then anything but I would like to fix it for my client. Any ideas ?
This is the tune.
