Which Tuning Level Do I Need?

Choose the level based on your existing modifications and/or goals. There are separate tuning levels for naturally aspirated (no turbo or supercharger) and boosted (turbo or supercharged) engines.

CSG Spec NA Level 1 - Stock Cars

• Stock Exhaust Manifold (Required)
• Stock or Upgraded Intake (OK)
• Pump gas or Flex Fuel (OK)

CSG Spec NA Level 2 - Upgraded Exhaust Manifold (header)

• Upgraded Exhaust Manifold (Required)
• Upgraded Front Pipe (Recommended)
• Pump gas or Flex Fuel (OK)
• Stock or Upgraded Intake (OK)

CSG Spec NA Level 3 - Upgraded Engine Internals and Exhaust Components

• Built/Upgraded Engine (Required)
• Upgraded Exhaust Manifold (Required)
• Upgraded Front Pipe (Recommended)
• Pump gas or Flex Fuel (OK)
• Stock or Upgraded Intake (OK)

CSG Spec FI Level 1 - For Engines with Unmodified Internals

• Stock Engine (Required)
• Supercharger or Turbocharger Kit (Required)
• Upgraded Radiator, Oil Cooler & Hood Vents (Recommended)
• Upgraded Port Injectors (Required for Flex Fuel, Optional for Pump Gas)
• Upgraded Exhaust Manifold (Highly Recommended for Superchargers)
• Upgraded Front Pipe (Highly Recommended)
• Upgraded Clutch (Highly Recommended for Flex Fuel supercharged setups, and all turbo setups)

CSG Spec FI Level 2 - For Engines with any Modified Internals

• Built Engine (Required)
• Supercharger or Turbocharger Kit (Required)
• Upgraded Radiator, Oil Cooler & Hood Vents (Recommended)
• Upgraded Port Injectors (Required for Flex Fuel, Optional for Pump Gas)
• Upgraded Exhaust Manifold (Highly Recommended for Superchargers)

Note: For boost levels below 1 BAR/14.5PSI on the FA20, and about 12PSI on the FA24, especially on pump gas setups, it is highly recommended to run the stock fuel pump. Aftermarket pumps do not offer more reliability here and in most cases, offer another potential point of failure.

CSG Spec tuning offers custom tuning application specific to the vehicle requirements through EcuTek tuning suite. Custom tunes are made from the ground up and cannot be shared to another platform, allowing for a truly customized experience for you. This customized tuning service is specific for your vehicle.

What does CSG's custom tuning service offer?
In our experience and extensive database of data acquired through thousands of hours of track testing and dyno R&D, "canned" tunes or "base" maps are never an "one-size fits all". Immediate gratification can be experienced quick base maps, but bespoke tunes specific to each modication list and individual vehicle is important to optimize and maintain consistency. Through extensive test parameters, we are able to develop maps that provide smoother power delivery, better modulation, improved drivability, stable power improvements, and better consistency under stress. No one wants a one-pull wonder, but everybody wants something that's repeatable and useful, especially on the racetrack.

Disclaimer: It is a risk to modify your vehicle from its factory setting which may void vehicle warranty and be non-compliant in specific organizations and sanctions.

Note: Due to high volume of calibration inquiries, sales, and projects that CSG is involved in, please allow, on average, 72 business hours (unless mentioned otherwise) for the preliminary calibration file and any applicable revisions/updates to be provided. This will allow our calibration team to reach out and ensure that the parameters are developed accordingly for your specific vehicle. Each vehicle is unique and our calibration team will work with you to optimize your vehicle's needs. Thank you for your patience and understanding!



All custom ECU reprogramming and/or tuning services offered by CounterSpace Garage are created in line with EcuTek's "Way Forward Initiative". This initiative is a framework within which the software itself, as well as all of CSG's calibration material, is utilized in line with the US EPA's requirements for emissions compliance. While most vehicles can still be properly tuned and drive / operate normally, some vehicles may exhibit DTC’s (Diagnostic Trouble Codes) due to certain physical modifications from factory. We will not, and cannot, deactivate these codes in ANY way, shape or form. Vehicles in this scenario should be repaired, brought back into compliance, or set up for off road use only (Non-Op Registration) for track purposes only.

Restricted changes include functions surrounding:


- Emissions critical Diagnostic Trouble Codes (DTC)
- Oxygen (O2) Sensors
- Three-way Catalysts (TWC)
- Stratified Warmup
- Evaporative System
- Features / tables, associated with certain OEM OBD Test Min/Max Limits
- Features / tables, associated with certain OEM OBD Test Monitory Entry Thresholds.
