Hallman has designed the Pro valve to not require the use of a lock nut or any type or Allen wrench(s) to be able to adjust your boost. Simply turn the adjustment knob and it stays. Another great feature is the fact that the adjustment knob cannot be lost or come out of the valve. Simply put there is not a potential for over boosting once set properly since the adjustment knob cannot vibrate loose and come out.
The Pro kit also includes: 3 feet of vacuum line, a mounting bracket, hardware packet and complete installation instructions all in one kit. This kit has all the installation hardware that is needed for most all turbo installs. Plus, it comes with a mounting clamp to hold the valve.

QUESTIONS & ANSWERS
Q: the only part I need to get more boost out of my stock 2011 wrx? jeffrey_sackett96920 5 years agoAnswer
The only upgrades I have made is a catback exhaust and injen cold air intake.
A: Any increase in boost without changing fuel trims can result in damaging the engine. It is not recommended to increase boost without having a proper tune.
