Using this Forge adjustable wastegate actuator is easy. First, when you place an order, make sure to tell us which turbo your Subaru STI has. Once you receive the product, it comes with a pre - set spring that works well for factory or slightly higher boost levels. But if you want more power, you can ask us to assemble it with a stiffer spring. When installing, keep in mind that we can't guarantee it'll work with every setup or increase the boost beyond what your vehicle's engine - management system allows. If your engine - management system can't handle the adjustment, it might cause problems, and we won't be responsible. This actuator is for Subaru TD04 / TD05 turbochargers. As for maintenance, just keep it clean and check for any signs of wear regularly. Also, remember that orders from Forge Motorsports may take up to two business days to ship out.
