I installed my XZT a few days ago and immediately noticed a difference in low end power and also a mileage increase. A few days later the power seemed less, which could be just me getting used to the addional power. I decided to check the flash sequence against the instructions and was getting a green/orange/orange which was not listed anywhere on the instructions. The led stays red when truck is running. Does anyone know if this is correct for an 06.

 

The flash sequence you are seeing is correct. It should flash green/orange/orange/green then stay red.

 

Take it off for a few days using the bypass plug. Then reinstall it. You'll feel the difference again.
