Did download without any additional changes yet. Performance has increased. Also sounds better. Very easy to do.

Install was not real easy, I had to update the software multiple times. Allow plenty of time to do the initial install, took me about 2 hours. Can't believe the performance improvement over stock. Haven't checked yet to see if any improvement on gas mileage (didn't buy it thought for gas mileage). Well worth it.
