    new injectors...

    I'm getting ready to install 42# injectors, just wondering what if anything do I need to do (computer wise). Do I need to get it reprogrammed or will they just flow? Thanks, B

    You'll definitely need the PCM tuned. I wouldn't even try to run it until it's been adjusted...that is, if you can even get it to turn over. It'll be extremely rich.

    Yeah, the PCM, if not tuned correctly, will think you are running the same injectors and therefore keep the same pulsewidth for the new ones, which flow more. So you'll pretty much flood the engine with gas if your not careful.
