All parts and components of the Pro Series controllers are custom CNC Machined.

The new adjustment system does not require a lock nut or a hex wrench to adjust boost, simply adjust the knob and it stays put.
Also if the knob is adjusted all of the way out it cannot come out of the controller. This new feature and design provides for a perfect overboost system since none of the internals can be lost.
You cannot lose your adjustment knob because of vibration or forgetting to tighten the lock nut like on the old style adjustment knob.
The Pro Series has O-ring integrity for precise control.
Every Pro Series boost controller may be easily upgraded to cockpit control by purchasing a newly designed add-on kit. Of course you will be able to buy it as an Evolution kit with the cockpit control already installed.
