Does anyone currently run the Quadzilla mileage max on their truck? Would you get the same mileage gain from a Xzillaraider XZT? I tow a 13K 5th wheel if one of these work better for towing.

The max mileage module gives better performance than stock, and better mileage about 10%. The XZT gives better performance than the max mileage, but slightly less fuel mileage, still better than stock. I have tried them both and for my use am using the XZT module. Yes power is addictive. LOL
