Hey everyone!

I was curious if boost Pressure should change much after installing an intake on these cars. I have the PRL HVI and I noticed that my max boost is 2-3 psi higher with the HVI than with the OEM intake and filter. I've verified this by swapping between the intakes and the difference is consistent and repeatable.

Is this normal? I was under the assumption that lower boost is better as that means the car is hitting the ECUs torque targets easier. Or maybe the OEM intake is more restrictive which in turn is limiting max boost pressure?

Interested in everyone's thoughts!
