Our E Tuning services set a new standard in terms of customer service and performance gains. The EJ25-powered STI requires a skilled tuner with closed loop boost control, optimal fuel and ignition control, and working with fragile pistons. Our tuner Alex is experienced with this platform and in optimizing these setups based on owner’s demands turning out multiple 400+Whp stock engine setups. Our E-Tuning system works smoothly and conveniently. You will simply log your car with your own Accessport on your own time and email logs back to us. This process typically goes quickly and smoothly. Please carefully select your options to ensure accuracy. Add any additional notes with your order.

We also offer tuning for MoTeC systems (which is available for the 2004+ STI and preferred on higher horsepower setups that require a second set of injectors) however, we ask that you contact us directly in our contact form for MoTeC support. Track support is included with any tune ordered in a specific time frame.
