Guess what I'm asking is if I'm seeing negative numbers on my screen the computer is to and would that not screw up the fuel mapping?? Cause the issue I was having before the new tunes was in town was grossly dirty and they are cleaner and now I've got negative boost...
Well you're only seeing a vacuum of 6 PSI at idle, right?

Has it always done this or is it new? If it's a digital monitor and it's always done this it could be the correction was set wrong or altered. They usually default to correct -14.7 for sea level, but you can adjust them as needed.

Just on the new tunes I got when I put older tune in my boost reading is fine

Then I wonder if there is something in the mm3 tuning where they can alter that and your digital reading is showing the difference from whatever they messed with.
