Do you mean bad boost as in higher or lower?
My car has a 3.4 and I only run a peak of 7.5 lbs. I know my car needs a tune, but I was wondering if getting a tune will make the boost go up. That would not make sense to me being that it is a belt driven supercharger and boost goes up with rpm. Just thought I would throw it out there and ask since some of you have been so helpful with the other stuff.
