I have it loaded on and it will only work in tow/econ mode. If I tune it to performance, extreeme or czy lry. than it will act like the trans retards the motor. What do i need to do?

Go to the bullydog wesite and look up troubleshooting. They may also have a technical assistance toll free number to call 1-866-BULLYDOG

it’s made not to take it because those chips hurt the engine. then when the engine breaks, people think it’s GM’s fault, and they take it in and tell everyone that their duramax broke. so this year, they have programmed the engine to not even take those. but i’m sure there’s a way around it if you MUST break your truck.
