Direct injected cars offer an increased level of efficiency and capabilities. However, the fuel systems are very expensive and difficult to upgrade when we want to extract more power from the engine. On top of this they have issues such as intake valves that get dirty. So it was time to innovate and allow you guys to enjoy a more powerful and safe Ecoboost!

The OEM DI fuel system in the 2.0 Ecoboost can deliver fuel for up to around 375whp but after this point it starts to run out in two main areas: The high pressure fuel pump, and fuel injectors. The high pressure pump is the first to lose pressure and this can cause driveability issues such as sputtering or non smooth running to redline as well as put the motor at risk of running lean. The DI injectors are soon to follow in terms of flow limitation especially if fuel pressure drops. Upgrades for these components are both expensive and in the case of the HPFP simply not available. Below is an image that is all too common of fuel pressure drops even when the car is making around 360whp without auxiliary fueling.

The Stratified Xtra Fuel System addresses both the HPFP and injector shortcoming with a single, plug and play auxiliary fuel system. Without any other upgrades there is enough fuel available for over 500hp even with the OEM in-tank fuel pump and even more if the in-tank pump is upgraded. Below you will see how fuel pressure stays up with the aux system above 25psi of boost with a GTX2867 turbo.

Installing the Xtra Fuel System is simple (simpler than a water-methanol injection kit) and it requires no cutting, splicing, soldering or any non-reversible modifications to the vehicle.

Once installed, the system should be tuned (tuning is needed!) to work in tandem with the OEM fuel delivery system for seamless and safe power delivery - especially when using ethanol based fuels that have higher fuel flow requirements. 

The controller is programmed using a serial/DB9 port. If you don't have a USB converter cable already make sure you purchase that option. 

Here are the dyno results of our shop car running the Xtra Fuel System and a GTX2867 turbo on on an E40 fuel mix.

What it works on:

Ecoboost 2.0T powered vehicles. This is a highly recommended fueling solution when running 350+whp with an upgraded turbocharger. 

More Details:

The Stratified Xtra Fuel System has some of these key benefits and features:

- More power is made throughout the power band safely. The system can support 550whp+.
- Running E85 blended fuel is now possible and safe without running lean on bigger turbos.
- A richer mixture keeps detonation and heat down which are major factors that contribute to piston and engine failure.
- Intake Valves are kept cleaner.
- A WMI port is included if you wish to run water-methanol injection as well. Aux fuel and WMI are a great combination when E85 is not available locally
- No splicing, cutting, or modifications of the OEM harness or fuel lines.
- Upgrading the port injectors in the kit (if ever needed) is cheap and easy. 
- Much better fuel metering and atomization than a WMI system - it is a proper fuel system that is also more reliable.
- No extra tanks or reservoirs or pressure regulators needed.
- Many OEMs opt to run both port and direct injection systems on their high power vehicles. This way you keep the DI system and efficiency and only use the port aux system at wide open throttle. 
- Fully Plug and Play. It includes everything for a complete installation.

Turn-around time: Up to 10 business days
