MKII Hybrid
Boost Controller
has been covered in Sport Compact Car (now SuperStreetOnline) and has been voted the World’s Best Boost Controller by The BoostLife.com , as well as countless customers.
The new MKII design maintains the proven mechanism and internal dimensions of the MKI, but in a smaller, lighter package. The HYBRID designation means that we use a low-mass synthetic ball in the mechanism. The use of precision ceramics in a manual boost controller was pioneered by Darren Dawes of Dawes Devices/3 Bar Racing Inc. Combined, these features make for a world conquering design, at a reasonable price. This is not your Daddy’s G-Valve!

The Dawes Devices Manual Boost Controller for Diesel Trucks
This version of our MKII Hybrid Boost Controller has a heavy spring for applications up to 30 psi (Diesel Truck). It CAN be used on a gasoline vehicle, but you may not be able to adjust it to less than 8 psi.
We've been making the fastest boost controller for over 13 years. Now we've updated it with a smaller, lighter valve body and new synthetics. Precision ground ball seat with custom angles that aren't even available on lesser boost controllers. 100% US made (no cheap Asian copies here), individually tested for 2 weeks, guaranteed for life! Install this boost controller and forget about it, because there is nothing better anywhere, at any price!
Our New Boost Controller Switch allows you to control two boost controllers to make a dual stage system. This switch is fully pneumatic and requires no wiring or power source, making for a fast and simple installation. The toggle switch can be easily mounted in the dash for easy use and used in any of the following ways:
1) Use stage 1 for on-road and stage 2 for racing (use this product with two Manual Boost Controllers).
2) Use stage 1 for launch and switch to the high boost mode (stage 2) once you have traction (use this product with two Manual Boost Controllers).
3) Use stage one for factory boost control and then switch over to your manual boost controller with stage 2 (use this product with one Manual Boost Controller).

All the features that made the original great, in a smaller package!
We used the same internal mechanism, but combined the valve body and fitting into one assembly. The net result is a lighter package, to keep shipping reasonable and pricing low. Plus, we’ve reduced the fill volume of the valve, which is always desirable for quick reaction of the boost controller. You can expect the same performance as the original TDI controller, in a smaller space.
Our MK II TDI is a boost controller with specific capabilities and fittings for the VAG TDi and Nissan Patrol Engine uses our new, Heavy Duty Spring.
Applications: All VAG TDi and Nissan Patrol applications w/VNT (non-VNT may use our Basic Boost Controller)
Purpose: To provide an inexpensive way to control boost fluctuations on the VNT engine.

The Dawes Devices FCE (Fuel Cut Eliminator) , eliminates the factory Fuel Cut on vehicles equipped with a MAP sensor.
The signal to the MAP sensor is unaltered until the cut-out point is reached, for full use of the factory fuel supply. Needed when you have raised the boost so high, the factory ECU is inhibiting your progress.
