Hi does anyone know where to get a replacement chip to run a zetec turbo on OFAB management on my brothers fiesta rs turbo. Its currently running 195 chip and 440 subaru injectors but I would imagine it is too lean for a zetec? Or any where that could live map OFAB? Don't really want to change the management to standalone if we don't have to as he only wants something around 230- 250 Bhp. Any one else running there zetec turbo on OFAB? Any advice much appreciated Cheers Dan
