I installed a MBC to dial down my boost from my WGA since it was doing 11PSI and giving super awesome fuel cut. No matter what i do it does the exact same thing. I didn't think this as a complicated device. No matter how far i turn it -- all the way to + or all the way to - its like i dont even have it installed
