The JET pcm was easy to install although it is a tight fit.Just be careful when reinstalling ECM -watch wires and weather strip attached to top of firewall.Be patient...it will fit back.One thing I was not aware of after the install and this may be a point to mention in the installation instructions was the BAS warning light came on after the first start-up.Don't be surprised if this happens.Here's what to do - start vehicle,turn steering wheel all the way to left then all the way to right then center wheel.After driving for about 4 miles the BAS warning light should go off & stay off. If not,you may have to check the pcm connection to ensure proper contact.With the JET pcm properly installed and seated on the ecm,there should be no warning lights lit on the dash display. As far as performance the first thing I noticed was the change in transmission shifting.It was smoother and the top end revs to shift went up 150 to 200 rpm (about 100 rpm below redline). Merging onto the freeway/highway & up to speed is definitely improved.Bottom end seems better also but I normally have the ESP turned on which would normally prevent/diminish wheel spin. MPG hasn't been checked yet.Overall I think it's a good product that is easy to install and so far hasn't created any negative issues. B.
