I have had it installed for about a month. Shifting is smoother under load, milage is up from 14-15 to a solid 17 and overall I have no complaints. I was a little leary removing all the fuses to do the programming but it all worked. I wish it had a better manuel but thats a small con. I was expecting a slightly larger device (like a GPS) but its not needed.
