street and strip. your fp will rise 1 pound for every pound of boost so if your running 17 pounds of boost your fp will be 60psi at wot.

But, were talking with line OFF right. So it wont be that high when you put the vacuum line back on the FPR.

You'll notice a 10PSI drop when you put the line back on.........AFTER setting your FP.
