Hello, I am new to these forums so bear with me here.
I have a 07 gt500 that has a TVS swap that's not quite running right. I had a tuner come look at it to find out that my calculated map is way too high. The car was reading ~180 kpa at idle and at WOT it was reading above ~500 kpa which I know for a fact the car isnt making 80 lbs of boost. All this is causing my fuel trims to be way off and the car runs way too rich. I'm not sure how calculated MAP works so I'm not entirely sure how this all works. I'm new to the platform so I'm not sure where to go from here. Are there any solutions to this?
