    Hey guys today i went and got my 4agze injectors sonic bathed/cleaned today and the guy at the shop said to me that the injectors are flowing good to 5000rpm but after that they start to go inconsistent with the flow in each injector. What does this mean ? do injectors lose there efficiency over time ? As i am going turbo with these injector and 5000 is where i start making power

    if your having problems with your GZE injectors, and your going to go turbo, you may as well get some 7MGE injectors... they're a straight replacement

    i'm not sure how much bigger than stock ZE items they are, but they are bigger witch will be useful if your going turbo and more power :2thumbs:

    if your using 365cc injectors and 5000rpm is were your gonna make power the injectors are way to small.
    even 440cc (3sgte) will be too small.

    so youll prolly start making power at about 2000 rpm and at 12psi those injectors will be fine.
    maybe the injectors wernt performing before the clean as well, you can try cleaning/testing them again.
