    Long tube tuning adjustments.

    I have 07 6.1 I'm adding long tubes too. Is there any adjustments I need to make besides adjusting fuel trims to tune. I heard there might be some adjustments I have to make if I move the o2 sensor back.

    New to this and having issues with O2 placement with Long Tube Headers. blowing P2196 code with stock Transort Delay. When you say multiply by 1.25, I am assuming you meen the transport delay map using the 'X' function. FYI the engine has a Whipple Supercharger and has been dynoed and tuned. But this is eluding us.
