Now you can fine tune your turbo actuator to the exact needs of your engine with this complete tuning kit. In your actuator tuning kit, you will find four or five springs (dependent on your actuator) and the associated spring retainer. The strongest spring is the red, followed by the blue, yellow and finally the green which is the weakest.
Please select from the options above if you require this kit for an 048 or 049 actuator. The 048 actuators are those with a big body, the 049 actuators are those with a standard size body.
Piston 049 acuators and diaphragm 049 actuators use the same springs.
The spring colour codes and their running pressures are as listed below.
T2 049 (Small) Actuator Springs (Both Piston and Diaphragm Type 049):
Green – running pressure 10 psi (0.7 bar) - spool up/opening pressure 5 psi (0.35 bar)
Purple - running pressure 13 psi (0.9 bar) - spool up/opening pressure 7 psi (0.5 bar)
Yellow – running pressure 15 psi (1.0 bar) - spool up/running pressure 9 psi (0.6 bar)
Blue – running pressure 18 psi (1.2 bar) - spool up/running pressure 14 psi (0.95 bar)
Red – running pressure 20 psi (1.4 bar) - spool up/running pressure 17 psi (1.1 bar)
T3 048 (Big) Actuator Springs:
Green - 10 psi (0.7 bar)
Yellow - 12.5 psi (0.9 bar)
Blue - 17 psi (1.2 bar)
Red - 18 psi (1.3 bar)
We normally supply our actuators, unless requested differently, with a spring that will match the tension of the manufacturer’s original fitment valve. However, as many owners undertake tuning modifications some may wish to re-tune the actuator characteristics to suit a given application.
Note: Serious or fatal damage may occur to the engine and associated components if this product is incorrectly matched to the individual engine requirements. Forge Motorsport nor any of it’s Authorised Distributors can assume any responsibility for any adverse effects resulting from the installation of this product
These kits are NOT suitable for our Diesel actuator for Garrett VNT turbos.
If you are unsure if this product is suitable for your application, please contact us.
*Please Note - The colours of the springs illustrated may differ to what you receive. All spring kits are brand new but are not sprayed. Colour is used as an identifier*
Please note that the quoted spring pressure against the various colour codes relates to the mechanical aspect only, applicable to earlier turbocharged engines that are not ECU/solenoid regulated.
However, modern ECU/solenoid engines do not require the target boost pressure to be matched pound for pound by the quoted mechanical specification of the springs we offer. Please take advice from an appropriately qualified tuner if you are unsure of the correct spring application for your model and the planned level of tuning.
For our T2 spring range (FMAS049):
• Red spool up/opening pressure 17 psi /1.1 bar running pressure/full stroke 20 psi/1.4 bar

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.

I have the actuator for an Abarth punto evo, 1,4 multiair but the spring that comes in it is not rated high enough. What do i need to order to make this right?
The Forge Motorsport Multiair actuator (T3 specification with part number FMACFPEVO) is not offered with anything stronger than the green spring which, in testing, proved to be the best option for both standard and stage1/stage 2 tuned models and is a highly recommended upgrade over the standard actuator (100% positive feedback). The stronger springs we offer for the T3 specification actuator induce overboosting in the 1.4 Multiair engines (without exception to our knowledge).

Hi, I have just purchased the recirc BOV for Audi S3. The kit came today which was excellent as only ordered yesterday. The kit came with a spring fitted in the BOV already and also a blue spring. Which spring would be used for Revo stage 2?
Please fit the blue spring. Please be careful not to dislodge the lid o ring before refitting the valve lid after swopping the spring as a broken or misplaced o ring will affect the valve function.

Hello , we do not offer an actuator for the turbo in question as the OEM actuator is controlled via a electronic actuator.
