Using your Boost Lab TD06SL2 - 20G Turbocharger is straightforward. First, make sure it's properly installed in your 2004 - 2018 Subaru STI or compatible WRX model. You might need to make some modifications if you're using it on a 02 - 07 WRX or 04 - 07 STI. Once installed, you can enjoy the extra power and performance on both the street and the track.
When it comes to fuel, you can use pump gas for a 450hp performance. If you want even more power, try race gas or E85, which can get you into the low 500 - hp range.
For maintenance, it's a good idea to follow the regular vehicle maintenance schedule. Check the turbocharger for any signs of wear and tear regularly. Since it comes with a 1 - year/unlimited - mile warranty, if you notice any issues, reach out to the manufacturer right away. Keep the gaskets and hardware in good condition, and if you need to replace them, use the included ones for a seamless fit.
