Being a college student I was looking for the most I could get on the least ammount of money. It woke my truck up (2003 dodge ram 1500 4.7L v8), acceleration wise and overall performance wise. Flowmaster exhaust seem to be a bit louder also. As far as gas milage, I live in a town where the speed limit is 30-35 mph and my gas milage has gone down about .5mpg. On the highway it was getting and increase of about 1 mpg.

Love the product easy to operate. Had a programer before on my challenger and was not very satisfied with it. With this one i could tell more power and butter fuel milage.
