Hello! I currently have an aftermarket BOV (turbosmart), and I was wondering if the CPE kit is worth the upgrade. I am using the stock vacuum pump line, not using intake manifold pressure, and I've heard that this blows off very quickly for safety reasons. This is my daily driver, so I wanted to be completely sure that using "real" intake vacuum will not lessen the longevity of the car. My last question is about the difficulty of the installation. I have seen some videos, and it seems pretty tricky because the space is very limited. I'm most interested in the kit with an HKS BOV, unless there's a better reason to get the kit with the Tial BOV. Thanks in advance!
