What’s the first rule of boost control?

Ensure you have an over-boost cut-out. This is safety feature built in to basically all factory, aftermarket & programmable ECU’s. The eBoost Range has an Over-Boost Shutdown feature built in aswell – You can never be too careful. Make sure it is set at a sensible & reasonable limit. Increasing the boost will put more load on your engine and there are other tune related factory you must always consider. If in any doubt, speak with a professional tuner / calibrator.


Can I use this on any turbocharged engine?

If your engine is turbocharged and uses a boost-based actuator for control, then yes. This Boost Controller will work on boost-based internal wastegate actuators aswell as external wastegates.


How much boost can I add?

This will come down to the rest of your setup & tune. If in any doubt we recommend you contact a professional tuner or workshop for advice here.
