Introducing the

JHM In Car Adjustable MBC

for the B5 S4(fits any turbo vehicle with minor modifications to our instructions) 

INFO:

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 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).

- B5 S4 specific instructions by JHM (will work on any turbo car with minor adjustments to our recommended install procedure)
