I have a 00 pcm. Im running 36 lb pontiac gtp grand prix injectors. I cannot find anywhere where the actual flow rate is. we got two answers of 45psi. when we calculated the new flow rate at 60psi the car will not run but if we upload the stock injector tables it will run but rich as hell to be expected. can anyone help me rescale these tables so i can adjust this property?

 

First of all, no injectors are flow rated at 45psi !!!! Injectors for GM cars are flow rated at 43.5 psi (3 atm) for 3rd gen cars and 4th gen LT1 cars. The LS1 car injectors are flow rated at 58 psi (4 atm).... Ford injectors are flow rated at 39.5 psi (so says the Ford catalog). I believe that the injectors that you are talking about are flow rated at 58 psi, but your flow rating may be wrong. Has anything else change on your car?
