Are you using the delivered LM1 PID or a custom PID?

There's been a few threads on differences between HPT WB readings and the actual WB gauge readings. You can create a custom PID based on the manufacturer's calibration table and just offset it by .3.

I think Bill has a demo in one of the stickies.
