    1997 Cavalier injectors

    I had a car come into the shop running 22lbs of boost. He replaced the 17lb injectors with 36lbs. How do I change the pcm so it will calculate correctly?

    The injector constant stock is .25573. So I take 17 divded by 36 equals .47222 times .25573 equals .1207613. Is .1207613 my new injector constant?

    As long as both injectors are rated at the same fuel pressure, you should be right.
