Truck runs pig rich in boost. ID 1000 injectors and walboro 255.
Have it commanding 13 to 1 afr right now and still pegging the
wideband full rich. Can someone look at my tune?

What is your fuel pressure at?

Is it still return style?

Fuel pressure is 50ish at idle and jumps to 60PSI in boost. I am looking at the FPR today.
Its return style. I was told to change B4001 to a straight line vs the sloping line I have now.

Yes return type the IFR should be the same for all, not sloped as for the returnless systems. This is likely the cause of your problem.
