Wacky VE scaling!

Wacky VE scaling!
I'm wanting to run more boost soon. I'm at 7psi now and I want 10psi soon. There's a problem with my VE scaling it's way off. It runs in the 212 kpa cells when I'm only boosting 7psi!!! It thinks I'm running about 15psi when it's only 7! Woweee!!!! The table maxes out at 230 kpa but I never reach those cells.
I've searched and no one else seems to have this problem. My tuner didn't know how to fix that. He said it has something to do with my MT his MT reads correctly. How can I fix this?
I want to post my MSQ, copy and past didn't work.

Because surely the solution is to introduce more variables.
Are you sure your configurator is set up for the correct MAP sensor? Is the correct sensor selected in the Engine Constants page?

So now I'm set for 250kpa map sensor. The VE goes from 14kpa at the bottom to 196kpa at the top. Is that correct?
I guess I will now need to retune my fuel and timing maps now that it should be reading pressure correctly?

Basically, you want your bottom-most row to be the lowest pressure that you expect to accomodate just short of decel cutoff, and the highest pressure to be slightly greater than whatever the maximum MAP you expect to encounter under full boost. (This latter decision is made to give the system a little bit of headroom in case you overshoot.)
