    What type FPR? What Pressure? And using what test condition?

    What RPM?

    What Pressure in the intake?

    How do you plan to tune it?

    What HP do you want to make sure helps....

    It is impossible to size stuff without this info. Se the EFI 101 thread for several calculators available on line.

    I thought V-Tech had the 1100's and maps for them and they were hoping people would use them? What speed are you seeing with iyour 2rude and what prop?

    I have customers that use 60, 80 and other versions.
    in most cases they are modded 52 lbs injectors, and this creates A LOT of troubles.

    The spray pattern is bad.
    The injector tips are to short.
    The voltage correction table is unknow - not linjear.

    And if they are not in our database we will not sped hours/days to make a map for them.
    We do have both 60 and 80 lbs maps in there but since yours can be different we cant guarantee that they will work.

    The VT11 are lower priced then the ID1000
    You will save a lot of time by using them.

    And you can use e85 in the future with same injectors.

    Scott you running a Motec??? 68/140 are seeing anywhere from 1-2 pounds of boost over a rude2. Not that it matters. Obviously he is using the wrong injectors for his "fixed" tune but "if" you have a motec in to which I suspect you are your flexibilty is vast.

    Hemi that 12.9 at 8600 rpm is dangerous
