I have a OBD1 GSR in my civic with a custom turbo kit. I have replaced the O2 sensor 3 times and the air/fuel guage reads lean until I get on the gas it goes to stoich. My car sometimes throws code 43 which is a Fuel System Supply code. I have replaced the fuel pump to a 255, new stock injectors(240cc), fuel pressure regulator, taken off the fuel rail and checked for clogs, new fuel filter and fuel lines. I have a vortech fmu 12:1 and currently running 7lbs. My car runs extremely rich under low rpm and starts leaning out as the rpms get higher. The car wont throw the code until after it boosts and under regular driving conditions. I have no idea whats the problem anymore. Anyone have any ideas on what this is??????????

Your problem is not Hondata related. Try Honda-tech or buy Hondata with boost option.
