Very easy to install yourself if you have some mechanical aptitude (not much, just some ;-)) - Since you have to remove the airbox and the wiring harness off of the old PCM and put them on the new PCM.
Keep in mind that you will need to get a case learn done from a dealer or someone else with a TECH 2.
