I'm anxiously awaiting getting my truck back from the shop. I have the Quadzilla XZT+. After installation, the tunes are downloaded to your computer & one power tune at a time may be installed in the XZT+ box in the highest setting. There are many power tunes available from the Quadzilla site & power tunes can be changed at will. Installing a power tune overwrites the prevous setting. (I believe the stock and economy tunes can not be changed.) I read about a "more agressive" non-published "3000 tune" on another forum. It is down loaded first to your computer then to the XZT+ box, the same as any other power tune. It is being shared by email so of course I had to have it. I can email it to anyone interested. PM me. Choice of tune depends on your use & trials on your individual truck. Thanks, Russ
