I posted this in the tuning section but hoping to get some gmt 900 specific advice. I can drive around with very light throttle but lose all power when I attempt to give it a bit more. I'm going to cause an accident driving around like this so I think I'm going to throw some parts at it. I figured I would get some codes if it was the TPS or coils but I'm not getting any. Let me know if you have any ideas what to test or what parts to try first.

This did end up being a tuning issue. Thank you to the member that helped me out all day yesterday! Hopefully I will be getting the Devil truck fully dialed in soon and making some power
