i know the shop that handled the production of the "kit" and they are very capable of one off cars but i doubt they would go for a mass deal like you are proposing ... which shop did you visit, sardis in north bergen who made the manifolds or that hell hole in newark ? bring a gun with you if its the hell hole ... or say hello to sardis if it was him, he's a good man with talent.

just to add: if they are going to use a full stand alone system on your car consider the cold start values will need to be tuned when the temps stop dropping or the car will become very unreliable towards the winter when it need to start up... this is a major PITA and you will need to do this on your own cause whoever tuned the car for drivability won't be there with you when you start it up in the morning...
