every setup will be different, folk have ran 250/300hp on jam/blitz ecus which obviously require bigger injectors. every jam/blitz ecu will also be different. some jams fuel great ct9 at 1bar, others fuel heavy, maybe they were mapped for a much bigger turbo. All guesswork and hearsay, but if you get a wideband on it and see whats going on you may get on alright. Seems odd to me to tune your car to a map and not the other way round, but so many folk are determined to do it. Phil
