APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 4.0T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

USP Motorsports is proud to offer a complete closed element air intake system for the 2.0T. After testing several designs, USP chose to go with a closed element intake system which is fed directly through the front grill of the vehicle.

The mass air flow sensor is joined to a closed element carbon fiber canister filter. The canister filter does not just look good but also performs. Constructed of carbon fiber and incorporating a high flow air filter, this filter was the perfect choice.

Finishing the intake off is USP’s patent-pending Tear-Duct. Not just a normal intake snorkel, the Tear-Duct has specifically been designed to allow maximum air into your engine.  As air enters the front of your vehicle it is captured and compressed at the Duct. As air moves through the Duct, it is further compressed by the “Tear Drop” design located at the rear of the duct. The “Tear Drop” not only compresses the air but also increases flow allowing more air to be pulled into the engine.

Dyno testing yielded exception power results through-out the RPM range. Users can expect to see gains of 8-16 wheel horsepower and 10-16 ft/lbs of torque at the wheels. Modified vehicles will experience larger power gains.

EuroCode ÜSS Billet Aluminum Rear End Links B8 / B8.5 / Q5 / C7 / D4 Chassis

EuroCode’s endlinks are the second part of EuroCode’s USS Stabilization system for the B8/B8.5 A4/S4/A5/S5/RS5, 8R Q5/SQ5 and C7 A6/A7/S6/S7/RS7 platforms, and is meant to be paired with our sway bars and Alu Kreuz drivetrain bar to work as a complete suspension system.  

A very common question is whether or not you will feel this upgrade on the street versus the track, and our answer is simple: absolutely.  The stock links are made from rubber which is inferior to our endlink’s billet aluminum construction.  If you just upgrade your swaybars without the links, you put more pressure on the OEM unit and reduce the efficacy of your swaybars. With this product, the weakest link is removed. Our end links will allow you to fine tune your suspension, reduce the flex and fatigue that is prone with the factory rubber end links, and allow for the corner balancing of the suspension.

The body of Eurocode’s ÜSS rear endlink is T6 billet aluminum with a clear type III hard anodize finish, laser engraved with Eurocode’s logo. Eurocode’s ÜSS rear end link contains a pair of replaceable spherical bearings with Teflon coated bearing races.

Lowering the ride height on factory air suspension equipped cars alters the geometry of the control arm and my produce a slight misalignment of the end link.  To rectify this situation, there is an optional fitment kit available. (Sold seperately)

These end links are a motorsport item and do require maintenence. Overtime the bearings will wear and create noise. We offer rebuild kits for both our front endlinks and rear endlinks.

Eurocode highly recommends rubber dust boots to protect and extend the life of the bearings.

Audi C7/C7.5 Eurocode Alu Kreuz Drivetrain Stabilizer

Eurocode Tuning's Alu Kreuz (pronounced kroitz) drivetrain stabilizer for the C7 chassis Audi's to include the A6, S6, A7, S7 and RS7. The Alu Kreuz replaces the factory multi piece drive train stabilizer with one solid, lightweight structural member to further stiffen the chassis and prevent unwanted suspension deflection. All 6 mounting points are secured to one single plane; the net result is sharper steering with a reduction in chassis flex.

Who would benefit from the addition of the Alu Kreuz?  We feel that if you enjoy spirited driving, like to take the on ramps and off ramps of the highway a little quicker than you peers, enjoy a nice drive through the canyons (twisties), the occasional track day or high performance driving class or just want to run your car balls out on the road course, the Alu Kreuz is perfect for you.

Testing:

During our testing of the 2013 and up C7 chassis cars which are comprised of the Audi A6, S6, A7, S7 and RS7 we found that there was quite a bit of torsional flex coming from the factory subframe/engine carrier. This torsional flex produced what we felt to be incorrect steering sensitivity and response in all aspects of driving. To combat this unwanted characteristic, we did a thorough examination of the front suspension, chassis unibody, and the engine carrier/subframe. Our conclusion was that the OEM hollow steel drivetrain stabilizer underperformed.

Design:

The team at Eurocode set out to combat this torsional flex and decided to redesign the drivetrain stabilizer. Our first step was to analyze the material that the factory stabilizer was made up of and then create a load case scenario in which to test it under. We sent out a sample for materials testing and found the factory stabilizer to be made up of carbon steel with a density of 0.284 lb/in3, predominately hollow and stamped into shape. The OEM stabilizer is made up of nine separate pieces, and they are all welded together to form one single unit. Once all of this data was collected and loaded, our team set out with the goal of improving chassis rigidity and weight reduction. Our team found that a replacement stabilizer manufactured out of billet aluminum would accomplish our goals, so the next step was the design process.

Our design process went through several revisions, with each version being loaded into computer modeling to test how it would stack up against the inferior OEM product; these revisions were also built and tested not only on the road, but as well as on a closed course with the feedback provided by a professional driver to the design engineers.

The finished product, which we dub “Alu Kreuz”, is incredible. It features a one piece, billet 6061-T6 aircraft aluminum construction, type III hard anodized coating, and all necessary provisions to attach the OEM sound deadeners. It requires zero modification to the vehicle, and works perfectly with the OEM power steering cooler. The Alu Kreuz is also nearly two pounds lighter than the OEM brace and greatly improves chassis torsional rigidity. It looks amazing as well.

Independent analysis was performed on the product and the conclusions were that in each of the pre set load case scenarios, the Alu Kreuz deflected less than the OEM stabilizer, carries less stress for a given applied load and the fatigue life of the product is greater than OEM.

SRM850 Turbochargers

SRM 4.0TFSI Exhaust Manifold with 

Integrated Turbine Housing

Our Upgraded Exhaust manifolds with Integrated Turbine Housings alleviate cylinder 5 miss-fire issues due to excessive back-pressure often experienced by people running stock exhaust manifolds and allow the engine to exhale freely thereby alleviating the major bottleneck in the 4.0TFSI engine. 

The upgraded exhaust manifolds are an integral part in the SRM850 kit allowing the package to reach such high power output by flowing significantly more than the factory exhaust manifolds without sacrificing the extremely responsive spool that the 4.0TFSI is known for. 

These same exhaust manifolds are proven well over 1000WHP on flagship and development vehicles and are the result of years of development.

SRM 4.0TFSI Port Injection Kit

Our Proprietary Port Injection Kit enables the SRM850 Package to run up to E100 and provides fuelling far beyond what the factory DI system is capable of. 

This port injection kit utilizes injection sandwich plates between the factory air duct and factory intake manifold for a drop in solution. 

Below we see the difference Port Injection makes on the SRM850 kit. The DI system topped out at 694WHP Mustang and our PI system allowing the kit to make 818WHP Mustang on this run on e60, and it is capable of flowing even more than this kit requires giving adequate overhead.

DS1 Software Calibration

Before today the standard in the 4.0TFSI community has been piecing together parts that then require custom tuning which is a headache and has mixed results. 

Hardware variance and lack of access to a Dyno for most custom tunes provides limited and inconsistent results. Dealing with custom tuners can be time consuming and expensive. Tuning without a Dyno and a tuner present to monitor the vehicle can be dangerous and expensive. 

We have addressed these issues based on feedback from our Customers and the Community in the SRM850 package by packaging the kit with a hardened calibration developed on our development vehicles on our in house Mustang Dyno. When you use the SRM850 kit, the calibration is already done. The tune is hardened and ready to use out of the box.

It's as simple as it is powerful.

Flex Fuel Capability

Our Flex Fuel System, Port Injection System, and LPFP upgrade, when used with DS1, allow you to fill up any ethanol percentage from E0-E100. 

No more worrying about overstressing your fuel system with high ethanol concentrations. This kit addresses fuel flow completely, allowing you to just fill up with Flex Fuel and enjoy your car. 

Simply fill up with any concentration of Ethanol, and the Calibration in conjunction with the hardware will account for your ethanol concentration seamlessly, adjusting power output accordingly to a given concentration of Ethanol.
