Also don't forget you will have to change to a complete ECU change.. I guess you can use a PowerFC but if I was doing this... I would go a full blown ECU.. like Autronic, motec and so on.. EMS (Engine Munching System) is never an option!! hahha So full blown of one those system is like 4k or so.. with all the trimmings.. Alot of money you better be serious.. haha i dont think your car would be considered a daily driver no more.. unless your going to be running top of the line semi on 7-8" wide rims.. imagine the cost of that every 4 months..
