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.
Check our our Youtube Video describing the benefits of flex fuel tuning on your EJ25-powered Subaru!
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.

The whole process of the e tune was straight forward and was an enjoyable experience overall! If you’re not looking for a full pro tune, this is the next best thing. Alex was incredibly helpful and provided a very detailed explanation on how to provide the datalogs. I haven’t had the opportunity to test out other e tunes but I’m not sure If I will need to. Alex’s tuning expertise really shows through as my tune didn’t really require multiple re-flashes. The car running and sounding great after the first re-flash.
