We then require you send all requested data logs back via email, and we will continue to send you revised files until your calibration appears perfect over datalogs and any possible calibration issues have been addressed. You will be sent a base calibration file based on your vehicle, modifications, and fuel type via email. Will require AccessPort number (ex: SUB0436555), and full modification list upon purchase.

You can simply flash these tunes with your AccessPort, without having a custom tune made for your car.Our custom remote tune for 2004-2021 Subaru WRX STi utilizing a Cobb Tuning AccessPort is one of the best ways to increase power safely without sacrificing driveability. Many intakes for the Subaru WRX will have off-the-shelf tunes available, such as the Cobb Big SF intake and Mishimoto Performance Intake. You'll hear the turbo spool up and hear blow-off sounds. Stage 1+ might add a bit more power over Stage 1, but the biggest change you'll notice is more sound from the intake. When the intake is modified, this will change the readings from the MAF, so some adjustments need to be made. With a different intake, the value it reads will change, so this needs to be corrected by flashing the ECU. The car senses how much air is coming in with a MAF (mass airflow sensor) so it can determine how much fuel to inject. Some additional tuning is required to keep the car running correctly when installing any intake. With the 2015+ Subaru WRX, the stock intake isn't very restrictive, and while an aftermarket one main give some small gains, it's small compared to the jump from stock to stage 1, or from stage 1 to stage 2. The difference is that an intake is added. In terms of powered added, Stage 1+ isn't a big jump from Stage 1. Just make sure that it's unmarried, or fully uninstalled from the previous car, you can't use it. The AccessPort costs around $650 new, but you can get one used for much cheaper. If you want to start modding your car, buying a Cobb AccessPort is a great place to start, and you'll need it to tune your car for any further physical modifications such as the intake and downpipe. Stage 1 tunes will also fix this, making the car overall much smoother and easier to drive. CLICK HERE for a list of known UNAUTHORIZED Dealers.

It also smooths out the powerband, eliminating the mid RPM dip around 4.5k present in the stock tune. It also smooths out the throttle, making it much more linear, fixing the oversensitivity of the stock tune. Stage 1 adds significant horsepower over stock, around 30 whp. ![]() The AccessPort also allows you to monitor some important parameters from the ECU, like knock correction, fuel trims, air-fuel ratio, intake air temperature, oil temperature, and more. It simply plugs into the OBD-II port under your dash, and with the press of a few buttons, your car will be Stage 1 in a few minutes. The AccessPort comes preloaded with tunes for the various stages. If you have a newer model, your only option to do this is using a Cobb AccessPort. This is the best starting point for anyone looking to mod a WRX. Stage 1 just means you've flashed a tune.
