Integrated Engineering Billet Manual Boost Controller ML Performance UK

Technical Details

With some careful engineering, we were able to design this unit to be adjustable from the base wastegate pressure to 30 psi+ without having to swap internal components for higher boost setups. That means the IE MBC is truly a one-size-fits-all unit and can be used with nearly any aftermarket turbo setup. Many boost controllers available simply bleed off boost pressure to the wastegate, which works to bring boost pressure up, but does not eliminate the wastegate from partially opening before the desired pressure is met. This makes for slower spool time and spiking boost pressure. With boost spikes, power delivery is not smooth, nor is it held until redline. We designed our MBC with a ceramic ball and a spring, so you can expect boost control to be linear and smooth with no concern for spiking. This style of boost controller does not allow any boost to the wastegate until the desired pressure has been reached, keeping it completely closed up until that point. Quicker spool time is seen due to that, making more power early on. The IE MBC uses a ceramic ball versus a steel ball, which can move much quicker and let boost through faster due to the material being lightweight when compared to steel. It is critical to have the ball move quickly, as it makes boost control nearly instant and keeps the boost pressure consistent.

Fitment Notes

  • Universal design that will work with any OE or aftermarket turbo
  • Will plumb into both internal or external style wastegates
  • A boost controller cannot adjust boost lower than the wastegate spring pressure
  • If you install your boost controller on a modern ECU vehicle, you may receive an overboost fault by turning the boost pressure above OE settings. You will need to run a software tune to allow manual boost control in this case.
