Hallman's Pro RX kit is essentially the Pro kit with a ceramic ball instead of a steel ball. This allows for very specific boost control, and very fine adjustment for those only raising their boost a few pounds above stock. Boost can be adjusted consistently in 1/2lb increments with the Pro Rx. For those looking to add more than 5psi, the Pro RX also includes a stiffer spring.
This kit has a ceramic ball instead of the 316 stainless ball that comes in the other Hallman Boost Controllers. The ceramic ball only weighs a fraction of what the stainless steel balls weighs. This weight difference allows the ceramic ball to act very quickly as it is constantly changing directions during operation. The ceramic ball in conjunction with the use of a lighter spring will allow very fine adjustment of boost up to 4 to 5 pounds of boost over stock. Boost has been able to be adjusted in half pound increments very consistently with this valve.
This kit was specifically designed for those that only wish to add a few pounds of boost over stock and have a great amount of control over those few pounds.
The kit also includes the heavy/stiff spring for those that would like add more than 5 pounds of boost and want to take advantage of the ceramic ball.
