I am looking for a manual boost controller to bump the boost up to 10psi before I go in for dyno tuning. I was wondering what the best way to get around this. The ebay MBCs look fine since it is just a ball bearing connected to a spring that allows air to bypass once it overcomes the spring. Is there really any reason to shell out $60+ for a brand name boost controller if my only goal is to increase the boost 2 psi and leave it there?
