    SRT-4 injector tuning

    Trying to figure injector percentage difference for base tune from a stock injector size at 557cc to new injector size at 2,200cc

    There's no single % change that will ever make 2200cc work at idle, cruise and WOT and also work for pump gas and E85.
    General rule of thumb, once you get past ~+40% over stock, that "method" will just give you more problems and force you to rape the VE to get the pos to run.
