It also has an economy (mode 1) that just changes shift points without added power, and a high performance (mode 3) that is supposed to add 35hp and 50 ft-lbs. of torque. I haven't used that yet because it requires 91 or higher octane . But I am very satisfied with it so far and Edge's customer support is awesome. I suggest them, but go to Autoanything.com, you can enter in your specific truck year make and model, it'll tell you what products are available, they have plenty of user reviews on all the products, and give you all the info on the product. Very helpful. Also they have free shipping within the U.S., they have a sale for 15% off for new customers, and there's no sales tax unless you live in CA like me.
