Tuning with 1.5 bar MAP (installed in a GEN 3 1 bar MAP PCM)

[86buick1]

Hi all,

Finishing tuning my LS3 swapped TA, and noticed my MAP readings are lower than others. At WOT I'm around 82.5, and KOEO I'm hovering at 85. I just came to the realization I have an L76 G8 intake manifold on the engine, which has a 1.5 bar MAP part number 12591290.

I have the tune set up pretty well, but am curious as to how does this affect my tune?

This is setup in a 2000 Transam, with the tune I'm assuming its trying to read a 1 bar MAP. I still have my original MAP, maybe it will fit?
