Stunned! Great product
I bought this tuner specifically for calibrating the speedometer for different rim and tire combos. And i thought i'd put the mileage tune in it as well. I took it for a test drive and honestly was shocked by how much it woke the truck up. This tuner is a great buy. I would recommend it to everyone that wants the most bang for the buck. Autoanything had free shipping options that included overnight and standard, i choose the overnight shipping, and it truly was delived in less than 24 hours!
