I have a 2017 Chevy Silverado 1500 4x4. I installed the 3.0 several months ago. Used it a few times. Last week while driving on the freeway in stop and go traffic the engine light came on and the engine shut off. After 30 minutes the engine started but ran in reduced engine mode as the engine light stayed on. Took the truck to the dealer and they said the Cam Sensor that communicates with the ECM failed. I removed the Speed Turtle 3.0 before taking it to the dealer. I am now worried that if I replace it that another sensor might fail. The truck was still under warranty so I didn't want to void that by having the Speed Turtle connected. The tech told me that it is rare a cam sensor would fail. I will let you know if I decide to put the Speed Turtle back on the truck. Sharing this just for info and I have no idea if the ST caused the failure.
