I live at 7400 ft and I'm trying to figure out the best way to get a DSP5 tune set up to work here. The issue that I'm up against is that the barometer here at my elevation reads about 11.2-11.3 psi, which would put me into the A tables for boost and B tables for timing. Since the DSP switching only happens in the C tables, essentially this means that even with a standard DSP tune, I'll never run in any of the tables other than A regardless of switch position.

The only potential solution that I have read about that would allow me to actually have DSP switching functionality here at elevation is to lower the barometer values in B2203 and B0907 so that the ECM always uses the C tables regardless of what elevation I'm running at.

What kind of problems would I run into setting up a tune like this?
