It took me 10 minutes to install, and 5 minutes of that was waiting for the truck to power down as I saw on YouTube. Unlock your truck, open the door, and get the key fob at least 30 feet away from it for five minutes. Install the PC then turn it on. This way you will not get a check engine light. It works amazing, I use city +2 and have no more lag with acceleration! It is wonderful!
