    6.0 with a supercharger wont run on correct injector data but will run on stock data

    Im having a issue and hopefully someone can point me in the right direction

    I have a 6.0 lq9 with a tvs1900 runing 42 lb injectors from magnuson.
    I have the magnuson supplied injector data and it has worked before on other installs .
    On this engine if i enter the Magnuson supplied IFR and offset data the vehicle will fire,Sputter and die.I can attempt to keep it alive using the throttle but its a near no go.
    If i keep the factory IFR and offset data the truck runs ,Idles and can be driven but my stft is of course pegging positive,and as soon as it enters any kind of boost wants to go Totally lean and cough/Sputter die.
    i can drive it down the road on the factory numbers at most normal speed but again cant get into boost.
    I cant drive it or even idle it on the correct IFR and offset for the 42lb inectors
    IF i keep the NA IFR but not change the OFFSET it wont run either,Both have to be changed
    But if i keep the VE tables the same across the board theres no affect.
    I have attached the log files for both

    Is there something im missing ?Where can i look to find a solution ?Are the injectors trashed?Is the data wrong?
    I dont believe i have a vacuum leak and i have partially ruled out mechanical issues since it will idle on the NA data but not even fire on the corrected IFR

    Any help will be appreciated Kinda at a dead end here

    Your files are tuner locked, can't really help you.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    using stock MAP sensor
    Should i at 15% to the IFR and leave the offset table alone ?

    Shoulda gone with a 2 BAR OS, you can't even tune the VE for boost with a 1 bar MAP sensor nor can you log boost with it either.

    No idea on injectors, never used them.
