After I installed the computer upon having it sent from Alex I've had zero issues at all. My X now has unbelievable performance and am VERY glad I did this. If you do this you will be very pleasantly surprised with the power and MPG increase. Start my drive from Florida to Wisconsin early tomorrow pulling a 3200# trailer. Before I did this I was averaging 16.5 MPG pulling the trailer. I'll report on the MPG's when I get to Wisconsin in a few days.

Alex also updated my computer as it was a while since that was done. He can better explain exactly what he did. He also reprogrammed it to get rid of the throttle lag like what the Sprintbooster would do.

Overall VERY happy with every aspect of this mod. I would never own a diesel without doing this.
