The Grimmspeed 3-Port Electronic Boost Solenoid has been a treasure to the turbocharged world of sport compact drivers. Not only has Grimmspeed designed this solenoid to work with our factory ECU (requires tuning), but this solenoid will outperform the factory solenoid by flowing better and reacting faster without having to use more power from the ECU. Additionally, Grimmspeed designed their electronic boost controller with a bracket to bolt into the existing provision in your vehicle, and it will come with an OEM-like connector to be a direct plug and play unit which eliminates the need for additional splicing. This also makes it possible to return your vehicle back to stock if you plan on doing so. 

EBC vs MBC. 

The manual boost controller will allow you to run a higher than stock boost level by preventing the wastegate from opening at its pressure rating. This does create additional boost however once you set your given boost target it will deliver that number throughout the entire rev range. This means that if you don't have the supporting fuel mods then you could potentially hit detonation at redline. Whereas you can tune the boost map in the electronic boost controller to provide maximum boost in the strike zone of the rev range and to overboost like some manual boost controllers can create. 

Other features of the Grimmspeed Electronic Boost Control Solenoid include ultra-low profile hose fittings that keep the unit as small and compact as possible. These hose fittings are nickel plated brass which makes them much more durable than the plastic hose fittings which are prone to breaking.
