I am selling my Hallman PRO RX Manual Boost Controller. I purchased this item new from JSCSpeed.com for $109 plus shipping. I have had it for 6 months, and it worked flawlessly. I just recently switched to having my UTEC control a BCS, so I no longer need this boost controller. This boost controller is great for someone who is looking to up their boost just a few pounds. The PRO RX model features a lightweight ceramic ball and a lightwieght spring which allows it to react very quickly, and also allows the user to dial in small increments of adjustment!!!! You can also get a heavier spring from Hallman if your want to really crank up the boost (it comes with it, but I lost it because I never used it. ) I only used this to raise the boost pressure up about 5 psi over normal wastegate pressure. It worked flawleesly on both my Turbonetics kit and on my greddy TT kit.

Here's what Hallman has to say:

Hallman Pro & Pro Rx:
Hallman's Pro valve is machined out of billet aluminum and stainless steel pieces. This updated design does not use lock-nuts or allen wrenches; simply turn the adjustment **** and it stays put. This eliminates overboosting as the **** cannot vibrate loose.

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.

Hallman also sells an accessory for this boost controller which gives you cockpit adjustability for thisboost controller!!!

 

Sold!!!!
