In what ways is the Turbo-Master better than the factory 6.5 GM setup?
The GM boost control is one of two types depending on the year model of the engine. The first type is the '92 - '93 mechanical injection engine with its spring loaded canister. This type applies a spring force to the waste gate lever to create boost pressure in the range of 3-6 psi. The second type is used on the '94 - '95 electronic injection engines. This type uses a vacume pump, computer conrolled solenoid valve and vacume canister to apply pressure to the waste gate lever. Boost ranges from 5-7 psi with this system.


Will I need a boost gauge to set the boost pressure?
A preliminary boost setting is made during installation. However, you will need to use a boost gauge to set the final desired pressure.

Is the Turbo-Master a part that I can install or will I have to take it to a shop?
TM installation is easy for most do-it-yourselfers. No drilling, welding, cutting, filling, or other fabrication is needed. Only simple hand tools are required. Installation time is 1 to 2 hours in most cases.

How is the Turbo-Master better than the factory Dodge set up?
The TM is fully adjustable allowing the tuner an ability to manage the turbocharger output to any of a wide range of pressure settings. Peak compressor output can be easily established and maintained. The factory canister type control is preset and not meant to be field adjustable. Increasing boost requires a bleed orifice (boost elbow) to fool the canister, which typically results in boost output ranging from 25-30 psi. The specific bleed-rate of the one fits all boost elbow affects each engine combination differently.

So what is wrong with the factory boost control system?
The factory device is ok for stock applications. The factory controller is designed to control the waste gate to a boost pressure of around 19 psi (Dodge) 5 psi (GM) which falls short of the pressure range in which these turbochargers produce maximum airflow and which is commonly desired for a modified engine.

Do I really need the Turbo-Master?
The Turbo-Master is not needed unless you require maximum efficiency and full rated output. You need the Turbo-Master control when your engine has been modified with fuel pump or computer module enhancements and or uprate fuel injectors. The Turbo-Master is used to raise boost pressure and airflow to a level, which corresponds to fuel delivery for greater power within the EGT limit. That means faster uphill towing speed.

Where does it fit and how does it work?
The Turbo-Master fastens onto the turbocharger as a direct, bolt on replacement for the factory canister type control. Turbo-Master manages the turbocharger waste gate valve to control turbine inlet pressure, which affects turbocharger shaft speed and compressor output (boost).

What is the Turbo-Master?
The Turbo-Master is the unique, fully adjustable, mechanical boost pressure controller designed to operate the turbocharger at peak efficiency and maximum airflow output.
