I load my file if I need to but simple? I hope .I'm on sd 3bar with the old fashion gm box sensor. Anyways I got a zr1 3bar.and my tune map sensor linear is 305.00kpa off set is 10.33 kpa but my new one is 312.0kpa off set is 12.0 kpa I switch that all over and truck ran like garbage so put original 305.00 and 10.33 it runs way better just ritch. Is it OK to leave at 305.00 even though sensor is supposed to be 312.00?
