Tried contacting Quadzilla with an e-mail and they were quick to respond.
The gentlemen that replied stated that "the module is one of our older products. The module is adjustable with an off, 50hp and 100hp settings. The 50hp setting is for increased mileage and towing and the 100hp setting is the performance setting and should not be used while towing also that it will work on 03-04 trucks."
I'm going to try and figure out if I can install this today and post up results when completed...
Get some di-electric grease and put a little on the connectors, then make sure they click into place. Last but not least wire tie the harness to the other harnesses in the area so it can't move around. I have had the same issues with my XZT box from quad.
