Accurate, Simple, Easy.
There are lots of boost controllers out there; they range in price from dirt cheap to wildly expensive.
Over the years we have installed many types and brands of Boost Controller. This boost controller is
everything you need to get the most out of your turbo BMW without emptying your pockets and with select features that we find make it one of the best manual boost controllers period for a turbo BMW, or any turbocharged project.
Chances are, your BMW didn't come turbocharged, so we have taken extra steps to insure we chose a MBC that is super accurate with a special valve design that eliminates boost spikes caused by slow valve designs. Look at it this way: an excess of 1 or 2PSI could be the difference between a killer ride and a killed motor...
Our MBC allows you to adjust your PSI whenever the mood suits and has a very smooth adjustment so you can make accurate increments as small as half pound (.5 PSI) easily.
250 step adjustment wheel allows easy, accurate hand adjustment, but will not loosen under high heat or harsh vibration when pressure is set.
Allowing from +0-60psi without having to switch springs, there is no more swapping out soft and stiff springs for higher or lower boost levels. Designed and made in USA from 6061 Aluminum.
The fast acting valve lets your turbo spool quicker by fully isolating the waste gate until pressure is reached, then reacting nearly instantaneously due to low mass. All electronic solenoid controlled types (Electronic Boost Controllers) must wait to get a signal from the boost sensor, process, then react by actuating the solenoid. This is slow, and it has been proven many times that this MBC outperforms both other MBCs and Electronic Controllers.
Other unique features includes is it's compatibility with the lower boost levels many turbo BMWs see Vs. nearly all other boost controllers that do not allow boost control below 15PSI*.

VAC Turbo Tech Notes:
Regardless of brand or type, a boost controller will only allow you to raise boost above the installed wastegate spring pressure. +0-60psi is over the default wastgate.
If you wish to lower boost level, you must run a lighter wastegate actuator spring. If your having boost spike/creep cause by exhaust related issues, no boost controller will fix this.
