Please check the measurements of your spring against those pictured before purchasing
Now you can fine tune your Blow Off/Diverter Valve to the exact needs of your engine with this complete tuning kit.
If you are finding that the valve is dumping more than required, or if you are losing boost pressure it is normally an indication that a stronger spring is required. Alternatively, if the valve is failing to dump it may be necessary to install a weaker spring.
Please note that fitting a stronger spring into a valve will not increase boost pressure, unless existing pressure is being lost. Failure to allow the valve to operate by installing a spring which is too strong, may cause damage to the turbocharger.
Please also note that the red coded springs should not be installed in the DVR or DV007 diaphragm valves.
Valve Spring color coding: Green - 5-15 PSI (0.35-1.03 Bar), Yellow - 15-23 PSI (1.03-1.59 Bar), Blue - 23-30 PSI (1.59-2.07 Bar), Red - 30 + PSI (2.07 Bar +)

Valve Spring Tuning Kit
All Forge Motorsport products come with a limited lifetime warranty. All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.
For further information, please contact our customer service team.
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.
