Your BPV needs to be open at idle. If anything you should loosen it. When i had the turbosmart on i had bought the lightest (blue) spring and even trimmed off a ring and a half to get the perfect amount of tension on the piston head of the valve. But, i did have the SI trim and 9psi pulley so it was pushing more air at idle. You should be able to trim down any of the springs to get the tension right.
