What I did was follow the advice in print instructions that came with all of my tuners, remove the tuner if you have to go into the dealer for work.
Out of sight out of mind.
Of course if your deleted then that’s a little more work.
Problem is my Derringer and iDash are properly installed and all the wires in the engine compartment and cab are carefully routed and zip tied for a very clean and professional installation. If I experience an issue on the side of the road requiring warranty roadside assistance, I must cut all zip ties, carefully remove all wires, Derringer and iDash BEFORE calling GM for assistance ... or risk paying for the towing fee plus all otherwise warranty-covered charges at the dealership. Now try doing this on the side of the road at -20 degrees F in a January snowstorm. As you can see ... removing the Derringer is not as simple as unplugging it from the OBDII port.
