    Not going to find exact data thats for sure.
    I did a quick google and from what I am seeing (could be wrong) the closest you may get is using the data from an 2006 Vette ls7

    This is also most likely BAD advice. Check out this thread/article...

    I agree that the best advice would be toget better injectors for sure!

    But if that is not an option for him at this moment getting "some" info would be better than none.

    Also as I said, I found that just from a quick google search as what others have started with.
    If it works or not is another story.

    The only way you'll get good data is to pull those injectors from the car and have someone with a nice flow bench characterize them... this is a long process on a static flow fuel system!

    That's like telling somebody the fuse on a bomb has ten seconds instead of eight, even though you really have no clue what it is. It doesn't really help.

    sorry was trying to help, found that from google search.

    guess just leave it all blank then lol

    really should not use those injectors but if he has no other option, something is needed for a starting point.


    Not sure why people still by these things, guess it is only because some people have been able to tune them (or think they have) otherwise no one would purchase them.

    Bad data can be worse than no data at all.

    You are guessing at best with regard to how they'll perform.

    It is a false economy to "save money" on cheaper unknown injectors when you will waste all kinds of time (money) trying to blindly figure out their behavior only to have the engine running poorly the whole time.

    He can either:

    1) replace the injectors with something that has good data and sell his to recoup some cost
    2) continue guessing and wonder why it doesn't run well
    3) stop whining and annoying people trying to help him when he doesn't like the same honest advice he's being given from multiple sources.
