Features & Product Details

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.

Excellent! 3 years ago

A must have purchase especially if you were going to tune. I recently went and got my 2014 Evo 10 tuned but before we did my tuner had me do a third gear pull and registered 27 PSI tapered down to 16 on the stock boost control solenoid. We then installed the GrimmSpeed 3 Port boost controller and it's now holding 26 PSI across the powerband tapering down to 22 absolutely a must-have

One of the best things for an evo x 4 years ago
5out of 5stars

There are two good things that you can do to an evo x to make it better, even if you are not really into tuning (like fear from strict emission standards), but a 3 port and a tune works magic, reduces lag, improves engine response, no more slow transition from 3k rpm to high revs, the whole rev band seems to work smoother. Just remember that you need wideband and tune, never install without it, and it is not rocket science to install it, anybody can do it, it is harder to remove the stock 2 port than to install this one.

  • Q: Would I...  whats a car?5 years ago

    Need to buy anything besides the boost controller to support it?

      A:  As far as parts go, this is all you will need. Everything is included to install it. You will need to have your car tuned after the install or you will over boost. Mike
