I know this has been talked to death but I`m going to ask anyway. I have the MM quad box & have been very happy with it. For $120 I can update to the zxt 65 hp software. I wont be able to turn it on or off just run it all the time. For a everyday work truck,will it hurt my truck? A little background, 06 with an auto. No mods except 295 tires. I pull maybe once a month for about 30 miles. I don`t need the extra power I just want alittle more when merging on to the four lane. No drag racing. Should I leave it stock or go for it? I would like to hear from the people that have run this box for awhile . Thanks

 

The 65hp tune will work fine and safely with your auto...and you'll appreciate the extra giddyup...
