Starting from
Starting from $825
PRECISION DIAGNOSTICS
Every tune starts with a full OBD read and baseline data log. We know exactly what your car is doing before we change anything.
STREET SAFE PERFORMANCE
Sharper throttle response, stronger mid range torque, and a power curve verified through precision data logging before you leave the workshop.
What changes when you tune
Sharper throttle response, stronger mid range torque, more even power delivery across the rev range.
Every car is calibrated individually with logged data and road testing. Results vary by vehicle condition and configuration.
The Process
Every vehicle follows our proven calibration workflow.
Hardware Inspection
We verify your Sherzad Haus Componentry and any supporting modifications are correctly installed, leak free, and meet our specifications. Any issues must be addressed before we proceed with calibration.
Stage 2 Mapping
We upload a calibration specifically optimised for high flow exhaust systems, upgraded intakes, and any other modifications. We adjust fuelling, timing, and boost control to suit the increased airflow through your engine.
Data Verification
We log sensor data across the full rev range, comparing before and after runs to confirm the gains are real and all parameters are within safe limits for your specific configuration.
Road Validation
A thorough road test confirms the car pulls cleanly through the entire rev range with no hesitation or driveability issues. We test in multiple conditions to ensure the calibration holds up in the real world.

Common Questions
What hardware do I need for Stage 2?+
Stage 2 requires supporting hardware modifications. The most common requirements are a high flow downpipe, upgraded intercooler, and sometimes an intake. We will assess your vehicle and provide a clear list of what is needed before proceeding.
How much power can I expect from Stage 2?+
Stage 2 consistently delivers noticeable gains above Stage 1 on a properly set up car. Results vary by vehicle health, fuel quality, and which hardware modifications are installed. We will provide realistic expectations based on your specific setup.
Is Stage 2 reliable for daily driving?+
Our Stage 2 maps are calibrated for street use, not track use. With proper supporting modifications and regular servicing, the car remains safe and reliable for everyday driving. We build these calibrations to last.
What happens if I install hardware without a tune?+
Running Stage 2 hardware on a Stage 1 or stock calibration can cause running issues, excessive exhaust gas temperatures, and potential engine damage. Always have the calibration matched to your hardware.
Can I revert to Stage 1 if needed?+
Yes. We can recalibrate to Stage 1 specifications if you remove the hardware modifications. We keep your Stage 1 file on file if you ever want to step back.
