I am thinking about making a plug-and-play COP kit for the turbo Buick. Right now, I have only tested it with an XFI. It would not involve any cutting or splicing, but would require you to come up with a way to mount your coils. It would have a built in 2-step and use the factory crank and cam sensors (or whatever else you have). Cost should be around $500-$600 for everything but coils and plug wires. Just trying to determine if there is any interest.
