  1. Simple install

    Posted by Robert on 3rd Nov 2013

    Seems to be a great product. I haven't run the car on the Dyno to see the true effects of the unit. Install went well. It takes a little bit of time to run the wires up front but once that is done the plug and play makes up for the time spent.


  2. Worked very well

    Posted by jake on 23rd Feb 2012

    Replaced a BAP on my 2000 Lightning.
    Very cool unit, worked great.
