Overall the product is decent. I find the economy setting very well programmed. The engine doesn't exceed above 2000 rpm unless you push hard on the pedal saving about .5-1 mpg. The trans only is my DD. The shifts in gears are very smooth but sometimes can be harsh in stop-go traffic. I've not used the towing only ,but I would expect it to be just like the economy setting. The performance or extreme setting is totally worth the money though. You notice right away the quickness of the acceleration. Torque also is very noticeable. It's a huge increase. You have to try it out if you do get this product. The only down side to this setting is that you have to have a 91+ grade of gas ,and it eats at your fuel tank really quick. Also there isn't five settings as I was thought to believe. 1.Trans Only 2.Eco Setting 3.Tow Only 4.Extreme My friend got one for the Ford ,and he only has 3 settings for his so just be cautious in realizing that this is what you want over other products but overall this is an excellent product.
