Stratified Automotive Controls

Fueling without compromise.

Our EcoBoost Auxiliary Fuel Kit is designed to provide all the fueling capacity most Focus ST, Focus RS, Fiesta ST, and EcoBoost Mustang builds need while maintaining OEM-like integration and drivability.

The system adds supplemental port injection using our in-house designed controller and a complete plug-and-play harness that integrates directly with the factory vehicle wiring.

Beyond controlling the additional injectors, the controller also reads ethanol content, making it an ideal solution for ethanol blends, larger turbochargers, and higher horsepower applications.

Compared to upgrading the factory direct injection pump and injectors, auxiliary port injection offers a more cost-effective path to increased fueling capacity while providing the added benefit of helping keep intake valves clean.

Simple installation. OEM-level integration. Serious fueling capability.

This is fueling done the Stratified way.

548 WHP on pump gas from the factory Subaru ECU.

This 2010 STI hatch came in with a serious build from Dales Autosport: a built motor, stage 2 cams, Precision 6258 turbo, rotated kit, front mount intercooler, and the supporting fuel and sensor upgrades to match.

Making power with hardware like this isn’t the challenge.

Making it drive smoothly, transition cleanly, and respond predictably throughout the operating range is where calibration becomes critical.

Using EcuTek, we developed a hybrid MAF and Speed Density calibration that allows the ECU to accurately model airflow from part throttle cruising to full boost operation. The result is great streetability when you’re off boost and 548 WHP when you’re in it.

The Subaru factory ECU is far more capable than many people realize when paired with the right calibration strategy.

Big power. Smooth drivability. One properly dialed in ECU.

Some cars are worth preserving. This one has made it to 313,000km.

This 2004 STI has accumulated over 300,000 km and is still being driven, enjoyed, and cared for the way a Subaru should be.

Equipped with a 16G turbo and supporting modifications and built by Dale’s locally, the goal wasn’t to chase the biggest dyno number. Instead, we focused on building a calibration that complements the car’s purpose: responsive, streetable, reliable, and enjoyable for years to come.

Using , we developed a hybrid MAF/Speed Density calibration and tuned the car on spring pressure (1 bar) to provide consistent performance while respecting the customer’s emphasis for response and reliability on his higher compression EJ motor. Even on spring pressure we made 57whp more than the stock turbo.

Not every build needs to be pushed to the limit.

Sometimes the best tune is the one that keeps a rally icon on the road for many more kilometers.

Here’s to the next chapter for this classic STI.

These cars are meant to be driven.

Fresh oil. Fresh DSG service. A little extra tire wear from proper enthusiastic use.

We tune these cars to be enjoyed—not parked.

Drive them hard. Maintain them properly. Repeat.

Take care of your car, and it will take care of you.

The best turbo setups aren’t just powerful — they’re enjoyable everywhere in the powerband.

In our latest video (full video on YouTube), we take an in-depth look at the PowerMax 2260S turbo on the Volkswagen Golf GTI Mk8 and show how proper turbo sizing, ECU calibration, and TCU tuning come together to transform the MK8.

440whp / 450wtq does just that.

A well-matched turbo should deliver:
-Fast spool response
-Strong midrange torque
-Efficient top-end power

Using the Accessport, we calibrated and installed the setup in-house on both fuel types. To round things out, the DSG was unlocked and tuned ( ) and all of this make the car feel cohesive under all conditions.

The result is a GTI that feels responsive and entertaining on the street while still delivering serious performance when pushed.

Power matters. Balance matters more.

Fueling to match the build.

Introducing our Brushless Low Side Fuel Pump upgrade for MK7 Golf R / GTI and MK8 GTI.

Built around an OEM-quality brushless pump and controller, combined with our in-house designed adapter harness, this LPFP delivers the flow, efficiency, and reliability needed for high-output setups.

Supporting 600+ WHP, this upgrade pairs perfectly with MPI system upgrades and is designed to handle the demands of E85 fueling and upgraded turbo setups.

Quiet operation. Efficient delivery. Seamless drop-in integration.

This is how a complete fueling system should be built.

Available now.

386whp / 404wtq on pump gas.

MK8 GTI with a Garrett - Advancing Motion PowerMax turbo and full bolt ons delivers a broad, flat torque curve, quick spool, and strong top-end pull. This is exactly what you want from a well-matched turbo setup.

Calibrated in-house on our dyno and flashed using the COBB Tuning Accessport, this setup focuses on usable power and consistent response, not just peak numbers.

Supporting modifications include a DSG unlock and tune by TuneZilla to ensure the drivetrain matches the engine’s output and bolt ons by CTS Turbo

This is what a well-rounded EA888 setup looks like on pump gas and stock fuel system.

Stay tuned for ethanol results!

This is where electronic wastegate actuators fail.

In Part 3 of this series, we’re looking inside a failed IS38 actuator to show what actually breaks — worn and damaged plastic gears inside the motor assembly.

Failure isn’t just age-related. These gears are sometimes overloaded when the wastegate arm itself becomes seized or difficult to move, forcing the actuator motor to work against excessive resistance until the teeth no longer fully engage. The MK8 has yet a different wastegate design showing how VW themselves have iterated through at least 3 very different designs with these actuators.

Diagnosing actuator health, wastegate movement, and load is a critical part of reliable boost control on MK7 and MK8 platforms. And now, when you get code P00AF you know where to look.

We live and breathe these interesting problems, hope sharing how software, tuning and hardware come together is also helping you guys!
