I would like to know if someone has tried ABT tuning stage 1 for the V8 4.2 that increases horsepower to 420hp..What is the 0-100 performance..And something else, what is the cost of the turbo kit ? Thanx in advance;)

I see nobody has replied to this yet so I'll tell you what I know. In my search for an S-Line in North America I came across the Abt several times and contacted them in Canada and the US. Both of them told me that in North America the Abt kits are strictly cosmetic although they both said that they could add a supercharger if I was looking to add more horsepower.

In addition, the kit can be put on pallets and shipped if you have a knowledgeable tuner shop at your location.

Let me know if you need contact information and I will post it or send it to you.

Hope that helps and good luck!
