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!
