Amazed at the instant horsepower gain. Gas milage is better. I will order one for my wife's mustang.

I have a 2008 jeep wrangler, I used this to help with gas milage and better pick up. so far looks like I have added about 1 to 1.5 miles per gallon and when you step on the pas the jeep have a lot better response. Just have to follow what the institutions say, I had no problem installing tunes.
