Here at BrenTuning, we offer a wide variety of tuning solutions. One of them is e-tuning. E-tuning is the art of tuning a vehicle off premises via e-mailing datalogs of critical engine data. To do this the customer would load the supplied BrenTuning base map and go out and do some wide open throttle pulls through a determined gear with the Cobb Accessport datalogging the run. The customer will then send those datalogs to us so we can tweak the necessary tables to make more power and improve drivability/fuel economy. After the tweaks are made a revised map will be sent and loaded to your Accessport and then car. This process continues until everything is safe, reliable and powerful. We do not limit you to revisions, revisions are unlimited within the first month. This means the faster you send us datalogs the faster you will receive your modified file. We do this full-time from a solid internet connection and work quickly, we hope the customer does the same. Most importantly, here at BrenTuning we offer a 48 hour window for revisions Monday-Friday.


$350.00 for all 2008+ WRX/STi Stage 1 and Stage 2 variations with a customer supplied Accessport. This will cover 30-days of revisions or until we find a safe and happy stopping point. Most e-tuning customers are done much more quickly than 30-days, but it is up to you to provide quality datalogs in a timely fashion. Revisions outside of the 30-day window start at $150 and go up from there pending modifications added along with proof of purchase of a previous e-tune. For bigger turbo setups please contact us for pricing. We do not offer e-tuning to customers local to us, as this has caused issues in the past.


Pre-tune preparation is up to the customer, as we are not responsible for aiding in getting the car ready. While we are good at diagnosing issues through logs, many people simply skip preparation, while tuning the car, this is critical. Any setbacks will delay the tune process.

This covers pump gas tuning only, flex fuel requires Cobb’s kit and there is an additional charge for that service.

Please make sure your car is 50 state emissions legal, the vehicle MUST have a cat in it.

    BrenTuning offers a top notch service. If you want to make the most out of your WRX/STi look no further. Customer service is the best of the best and responses are extremely fast. BrenTuning made me fall in love with my STi all over again with the magic they worked on the tuning. I highly recommend this service.
