Installation is so easy a cave-man could do it. After installled response improved significantly. Not near as much lag as before using product. Mpg's seem to be silghtly better.I would say aprox .5 mpg better. So if you do the math it wont take long before this product pays for its self and then SAVES you money. Overall a good purchase I highly recomend for all drivers trying to get a little more out of there vehicle.
