QUESTION OF THE MONTH

 

What is the difference between the Pro/Evo and the Pro/Evo RX?

***The Pro/Evo RX comes with a ceranuc ball and a light spring. This allows for for finer,smaller amounts of boost. Typically, boost can be controlled in half pound increments. The RX version is designed to max out at around 6-7 psi with the ceramic ball and light spring. This kit also comes with a heavy spring. The spring can be changed for additional boost. This works well for most applications.

 

***The Pro/Evo has a steel ball and heavy spring installed. You cn expect to start adjustments at stock levels and go up from there.
