For their 4.0TFSI.

Drop in package that includes everything you need to make up to 1000WHP.

  • Xona Billet Turbochargers for 4.0TFSI
  • Upgraded Exhaust Manifolds with Turbine Housing for 4.0TFSI
  • SRM A2A with Port Injection for the 4.0TFSI
  • SRM 3" Intakes for 4.0TFSI 
  • LPFP Upgrade for 4.0TFSI
  • Ethanol Sensor and Lines Kit for Flex Fuel
  • Tial Wastegate Actuators for 4.0TFSI
  • Software Calibration for DS1


This kit has consistently tested at 950-1000WHP on our in house Heartbreaker Mustang Dyno, which is well over 1100WHP DynoJet. The highest performance kit available for the 4.0TFSI platform.

SRM1000 Billet Xona Ball Bearing 


Our SRM1K Billet Turbochargers are the result of years of research and development bringing the ultimate drop in Turbocharger solution to the 4.0TFSI platform. These have been powering our Flagship and Development vehicles for years.

Limitless top end with mind numbing boost numbers.

Why Xona? It's simple. They're USA made, rebuildable, and offer the highest possible performance in this form factor. Xona Turbochargers power our flagship and R&D vehicles making upwards of 1200WHP.

SRM Air to Air Intercooler with 

Integrated Port Injection

One of our flagship products, and first to market in the 4.0TFSI world, the result of years of development and iteration, is the 4.0TFSI A2A with Port Injection offering from SRM. 

This gorgeous piece has billet CNC end tanks, a large core, and integrated port injection via billet CNC snouts. This is the crown jewel of any 4.0TFSI and is every bit as functional as it is stunning. 

The A2A keeps charge temperatures low during a pull, and the Port Injection integration allows use of ethanol concentrations up to E100.

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 SRM1000 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 on flagship and development vehicles and are the result of years of development.

SRM 3" 4.0TFSI Intakes

The big brother of our SRM 4.0TFSI Intakes, the SRM 3" Intakes, are a requirement, allowing the Turbochargers to breathe well and are a significant upgrade over the stock intakes which are a known bottleneck on this platform due to their restrictive design. The inclusion of the A2A in this kit allows the larger intakes to fit.

SRM 4.0TFSI LPFP Upgrade

Essential to deliver enough fuel to the Factory Direct Injection and Port Injection System to achieve these power levels is the SRM 4.0TFSI LPFP Upgrade. 

Proven dual LPFP solution that we have offered for years. These kits are extremely reliable and provide the heavy lifting for fueling the SRM1000 package.

Flex Fuel Lines and Sensor

To enable Flex Fuel use on the 4.0TFSI, the flex fuel lines and sensors are required. This with DS1 allows the kit to utilize flex fuel.

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 SRM1000 package by packaging the kit with a hardened calibration developed on our development vehicles on our in house Mustang Dyno. When you use the SRM1000 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.


  • C7 & C7.5 RS7, S7, S6
  • D4 S8/A8 (4.0TFSI)
  • Requires DS1


  • This kit must be used in its entirety!
  • Failure to do so will result in the kit not being eligible for calibration or technical support!
  • Meaning : The kit must be implemented completely, and you are only to omit required parts of the kit if you already have them. Failure to adhere to this will result in you being denied support, calibration, and refund! However, if parts of the kit are omitted accidentally, please contact support and we will help you order them and regain access to calibration and support. If you omit parts of the kit, and an issue arises that could be attributed to the omission of said part in the build, we will ask you for photographs of the parts you omitted in the order installed on the vehicle before proceeding with support.
  • The base of the kit, the SRM1000 Turbochargers, SRM1000 Exhaust manifold and SRM A2A with Port Fuel Injection setup is by default part of the SRM1000 kit and no substitutions or omissions can be made on the core of the kit.
  • The supporting modifications included in the kit, SRM Intakes, SRM LPFP, Ethanol Lines and Flex Sensor package, Full 3" SRM Exhaust and Tial Wastegates for the 4.0TFSI, may only be omitted if you already have them! No exceptions!
  • The SRM1000 kit REQUIRES a DS1 for calibration. You must already have a DS1, or select one from the add-on menu. 


  • A TCU Tune is REQUIRED and is available as an add-on
  • This kit is for Off Road Use Only and should be installed by a professional.
  • Requires sending in Exhaust Manifolds as cores prior or a core charge of 1000$ will be required
