Did not adjust as many items as I thought it might. Easy to install. Just wish it did more for my truck.

Before anything - go to website and update the programmer... Didn't work on my F150 - an error code + call tech....Online follow-up - they want you to send them the unit for updates... It did however work as described for my GT. Site does not explain how to do multi cars while storing the stock settings.
