I want to increase a bit more horses from the factory boost. I thought of deleting the CAT, but i didnt want to bare the hassle of CEL and increase in fuel consumption seeing as gas prices are on the rise. Maybe increasing the boost would settle this problem. Maybe to 10psi since factory internals can bare 15. Am i safe to run 10psi on only a fmic mod?
