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?

 

check out www.boostvalve.com i've had one for about 4 years and it has never failed me once. I bumped my boost from 5.5psi to 10psi (old turbo) and it held steady with no problem, then most recently I used it to bump from my 9psi sping to 13.5psi and it held steady. Never had any issues with spiking or creeping. Best of all it's cheap.

 

Thanks alot. That looks like just what I need for the price I want.
