I am afraid I may be addicted to the GFCP. Currently, I have Cartech Twin turbo system on my OBD2 car and am seriously considering the FX500. I would be looking to sell my system which includes 2 t-28 turbochargers, stainless exhaust and all of the hardware including the Rebic IV auxiliary injector controller. I am looking for the best offer over $4000. Tim
