Chip tuning changes the engine management software. GTR develops a calibration for the vehicle and can check the result on its own dynamometer.
Before changing the programme, the engine, boost, fuel and cooling systems should be in good condition. A calibration should not conceal a fault already causing poor performance.
The achievable result depends on the engine, vehicle condition and hardware limits. Power, torque and fuel savings cannot be promised as one fixed figure for every car. ECU shipment from other cities is available by prior arrangement.
Compatibility and objectives
Before calibration we confirm the engine, ECU, transmission, condition and existing modifications. The objective and scope come first.
Verifying the result
The verification method and need for dynamometer measurements are discussed in advance. Race-project figures belong to those configurations and do not carry over to a standard road car.
What determines the price and timeframe
The estimate depends on the vehicle, diagnostic scope, required work and parts. We agree the task before starting; additional work is discussed after inspection. Timing also depends on parts availability. For a quotation, provide the VIN or model, engine and symptoms.

Before your visit
Can a power increase be guaranteed in advance?
There is no universal increase for every vehicle. Results depend on the engine, control unit, condition and installed components. The calibration target and verification method are agreed for your car.
What information is needed to discuss a tune?
Model, year, engine, transmission, existing modifications and your goal. Existing faults need investigation first. A dynamometer measurement is arranged separately.
How do I get a price and timeframe?
Send the VIN or model, engine, mileage and a description of the work. Cost depends on condition, required parts and scope, and is agreed before repairs.
Should I book in advance?
Yes. Contact the workshop by phone or email first so we can confirm the work, parts availability and a suitable time.
