    I have a 2017 t680. I’m having an issue of the check engine light coming on and it cuts about 15 to 20 % of my power and it stays on about 10 seconds and goes back off and gets power back. It does this only on a pull. But it doesn’t throw a code or any faults. Anybody have any ideas??

    That's normal for a 350 small block Chevy when it's cold. Check your spark plug connections........Come on guys!
