Stage 1 on diesel and petrol: where is the difference felt the most?
The result of Stage 1 optimization depends mostly on the design of the engine, turbine, factory reserve, fuel and technical condition. The same percentage increase cannot be promised for every vehicle.
Turbodiesel
With turbo diesels, drivers most often notice higher torque in the mid-rev range and easier intermediate accelerations. The limits are determined by the turbine, injection, clutch or transmission, DPF and the overall condition of the engine.
Turbo benzinac
Turbo petrol engines also often have visible room for optimisation. The result depends on the quality of the fuel, temperature, ignition system and the factory version of the engine. Correct spark plugs and coils are especially important before increasing the load.
Naturally aspirated engine
With engines without a turbine, the space for increasing power by software is usually significantly smaller. Changes in the response or behavior of the throttle are possible, but you should have realistic expectations and not compare the result with turbo engines.
Pre-assessment check
An exact quote requires model, year, engine designation, factory power, and information about previous modifications. Take a look at the catalogue Orientation Stage 1 Capabilities, and the final value is confirmed only for the specific vehicle.
An overview of all related interventions is available on the page on the Stage 1 optimization.
Submit the model, year and a brief description of the problem. We will answer what needs to be checked before the appointment.
