DETAILS

The JB4 is the most advanced and highly featured tuning system available for your 2022+ Subaru WRX 2.4L 4 cylinder turbo. Power gains are up to 50hp to the wheels (70hp crank) on a completely stock car on pump gas, gains with ethanol mixtures and bolt-on parts are even higher.

The JB4 features a simple plug & play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly map switching from your phone/tablet instead between factory and various performance maps, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, and much more.

Installation Instructions: 

Does it come with the app adapter thing to use your phone? 

The connection to the app is wireless over Bluetooth. This comes with everything you need to install and monitor.

Can this be used on the wrx gt which is an automatic i noticed it says you can tune the shift and gears and just wanted to see if this will be compatible with the automatic version before purchasing? 

Yes this works with your 22 WRX GT automatic!

I was curious if this is in stock as of 91522? 

As of September 18th 2022 we do have them in stock. It is recommended that you place your order immediately as we cannot guarantee they will stay in stock.

Honest question that i cant seem to find an answer for what increases could i expect on 91 with intake exhaust are there any dyno runs to back any gains up thanks? 

When running an intake and exhaust octane is required to reduce knock. It is not recommended to run anything lower than 91 with aftermarket performance mods.
