    I didn't think so. I thought the ecu map was different to get the extra 5 ponies..

    I have been asking this question for some time now. Some say 42's and some say 48's... Is there any way to confirm the injectors size by looking at the injector or must you flow them to be sure... Or...can anyone confirm the size???

    ok dear friends, I bought AFR waiting for my arrival the only way to not pierce the pistons and check the color of SparkPlug. The response I received from LESS COOKE stock injector that are good but do not have to exceed 8500 RPM's, I also wonder if my PWC use pressure regulator bank because I can not overcome this? when my full trotle is open I have a pressure increase equal to the pressure of the turbo, then it means that my blood pressure from 60 PSI 75 PSI becomes approximate, so I think that even if my ECU reflash is calibrated to 8500 with stock injectors but I overcome my 8500 regulator pressure should give me more gasoline to have a good AFR correct? . Yesterday I spoke with a technician from INNOVATE and I said that I will send a written sheet with the approximate values ​​for a proper AFR based on the pressure you are using. Hello everyone and THANK YOU
