FAST  B2B  late model unit (2004) , with  Caspers Buick V6 harness, laptop wires , new 02 sensor (not original ),  and injectors  $550 Shipped . There's nothing wrong with this unit , I purchased it from a Turbo Buick member,  It was installed   on my car  a few years ago for about a week , the car ran rich , I was told I needed additional software and tuning , I took it off the car and it's just been sitting in the closet ever since,  what you see in the photos  is all I have , thanks!
