"I am very pleased with the module I purchased for my 2011 Jeep Liberty, the vehicle starts faster, has smoother and quicker acceleration, the transmission shifts better and it just overall made a big difference, I have not really checked yet to see if it helped with gas mileage but I'm not sorry I bought it.
