JHM - Manual Boost Controller - BLACK (in car adjustability) for Audi 2.7t (NLA)

Improve your turbo response greatly and set your maximum boost limit. This is the lowest cost and most reliable in car adjustable solution without expensive electronics. Note: most successful with our Tuning software.

JHM is proud to be selling this patented design produced by Hallman. This MBC is integrated into a self contained cockpit controller cable system. The self contained cable system will allow the user to control and adjust boost from inside the car. This new system makes it very easy to set initial desired boost level as there is no need to stop the car, open the hood, make an adjustment, and then drive the car and see what boost is. Then repeat the process if boost is not at desired level. JHM has tested over 5 different MBC designs and this one is by far the best. We are only selling them with the Steel ball since in our testing this is what works best with a B5 S4 (there is a ceramic ball option, but not recommended for the B5 S4).

Includes: B5 S4 specific instructions by JHM (will work on any turbo car with minor adjustments to our recommended install procedure) - Manual Boost Controller with 72 inch long integrated cable and Knob for in car control - JHM Provided hardware in addition to the Hallman provided parts to make it an easier fit into the B5 S4 - MBC mounting bracket - 3 feet of vacuum line (not needed for a B5 S4) - Light and Medium Spring - Hallman general installation instructions - Kits are available in Black(Most Popular), Red, Blue or Purple(special order). Use the drop down box below.

NOTE:This kit can also be ordered without the cable, however all adjustments must be done from inside the engine bay setup this way.
