Hi i just recently purchased forum member Dusty_Duster's 93 duster and am looking at purchasing a turbo and getting a custom 3bar calibration....my question is other than throwing the +40 injectors in as he had prepared the car for everything else for stage 5 calibration on the 3 bar map sensor install do i need to modify the wiring harness in any adding wires and adding pins to smec etc.. or do i just get the pigtail connector and solder the connections to old wiring for the 2 bar map sensor?
