Save your money and buy a SCT and get custom tunes for your 6.0l.

I agree, sounds like smoke and mirrors. What caught my attention first is the horsepower vs. torque gain. They are almost even and that usually doesn't happen with our motors.

I is a cheapo version of the earliest modules made for the 6.0 before the tuners cracked the PCM codes. It will do something but is it timing,or fuel?

Dont waste you time.
get even an "out of the box" sct tuner and you will be way further ahead.
