Engineered For Performance
Thank you for purchasing the Forge Motorsport UNOS manual boost controller. We are highly confident
that you will find this product to be superior in its quality, performance and user friendliness when
compared to all other manual boost controllers available on the market today.
Before installing this product, however, please be aware of your vehicle’s OEM boost control system and
the routing of vacuum/pressure lines. These intricate details are specific to each application and will effect
the installation, mounting location, and tuning of this product on your vehicle. Also bear in mind that this
product is universal in nature, and as such, these fitting instructions are generalized to aid in ease of
installation on multiple vehicle applications.
Ref. 1 - This port on the UNOS
manual boost controller is the inlet
of the unit and needs to have a
pressure source taken directly from
the outlet of the turbo or from the
intake manifold. We highly
recommend and prefer that the
source be taken from the outlet of the
turbo or from the intercooler piping
as close to the turbo outlet as
possible, but the intake manifold can
be used if no turbo outlet source is
available on your application.
_____________________________
*Production units may vary slightly in their appearance but the port
locations and references will remain the same.
Ref. 2 - This port on the UNOS
manual boost controller is the outlet
of the unit and is to have a pressure
line connected to the pressure
reference on the wastegate actuator
of your turbo or external wastegate,
depending upon whichever is used
on your application.
There are two springs included with the UNOS to allow for a wide range of adjustment, however, there are
no guidelines as to which spring is best suited for a given boost pressure level on any given application.
This will be based entirely on the base spring pressure of the wastegate actuator or external wastegate used
on the application in question. If the softer spring installed in the UNOS does not provide the level of boost
adjustment you are looking for, you will need to then use the stiffer spring in the unit to reach your desired
level of adjustment. This will likely require some trial and error before you are able to reach your desired
boost level.
Please DO NOT install the UNOS manual boost controller in the opposite orientation or with the inlet and
outlet ports connected to the opposite sources from those that are recommended above. Doing so will
prevent the unit from operating properly and may eventually cause damage to the mechanical components
of the engine or turbocharger if not installed in the correct way immediately.
When changing the springs in the unit to a stiffer or softer spring based on the needs of your application,
please be absolutely sure that the first and possibly the second spring coils are wrapped around and securely
seated against the adjustment base/perch inside the unit itself. This is necessary for proper actuation and
performance of the unit. Failure to properly seat the springs onto their base/perch may result in an
inconsistent level of adjustment and boost response. Please see the pictures below illustrating proper
installation of a spring onto its perch.
As they’re small and easily misplaced, please put the spring that you’re not currently using somewhere safe
that you’ll remember if you need it later. Replacements carry a charge of $3.00 each.
If you have any specific questions or concerns about the installation or tuning of this product on your
application, please contact your preferred Forge Motorsport authorized dealer, your vehicle’s tuner, or you
may contact us directly.
