Description

We are glad to provide custom E-Tunes for the 2004-2020 STI based on our years of dyno tuning knowledge. With all the different performance part combinations, a one size fits all staged tune isn’t always the right choice. We take into account all the modifications you have along with your goals/expiations to give you the best driving/performing car. We also know the limits of these engines and know where in the engine rpms it’s safe to push them and where it’s not.

Stage 2 Power

With a stage 2 tune, you can expect peak power increases of 16% HP and 29% FtLb TQ. You can expect to get 30-40 horsepower increase throughout the whole rev range. Check out our Mods Guide to see dyno graphs of power outputs and for a good mod path for future modifications.

Open Source E-Tuning

With Open Source E-Tuning, more is required from the customer than E-Tuning with an Accessport. You MUST have a laptop and be able to install the Open Source programs Romraider – for logging and ECU Flash – for downloading and flashing tunes to your vehicle’s ECU. We will provide all the download links and detailed instructions on how to download the programs. Romraider is a free open source program created by enthusiasts like you. The installation process of Romraider is more involved than commercial programs but nothing most people can’t accomplish.

You will also need a wideband AFR gauge like AEM or Innovate. The gauge will need to be wired to the ECU or use a serial adapter to log with Romraider.

Features included for most years:

  • 2008+ Boost By Gear: All MT tunes have boost by gear. This helps your car hit close to boost target in all gears
  • Smoother boost for more linear power delivery
  • High Gear Over-Boost Protection: We employ over-boost protection in 4th-6th to limit boost below defined rpms. An example is if someone goes WOT in too high a gear at too low an rpm, boost is limited to wastegate pressure to keep engine loads low and reduce the risk of engine damage.
  • Launch control / Flat Foot Shift: Available for most years
  • Speed Density: Available for some years
