Power and torque gains calculator
See what a Stage 1 calibration is worth on your car before you buy anything. Pick a make, model and variant and the calculator shows the stock figures next to the tuned ones, in bhp and Nm, straight from our own vehicle database.
- Stock versus tuned, power and torque
- Figures from our own catalogue, not estimates
- Petrol and diesel, Stage 1 through Stage 3
- Free to use
How it works
- Pick your vehicle Work down from make to model to generation to the exact variant. Engine codes differ far more than model names do, so the variant is what decides the numbers.
- Read the gain The calculator shows stock and tuned power and torque side by side, with the difference called out separately.
- Upload your file When the numbers look right, upload your ECU read and the matching calibration comes back in about a minute.
Typical Stage 1 gains
A sample of what a Stage 1 calibration returns on some of the most common variants we see. Your own car's figures depend on its exact engine code and condition — the calculator gives you those.
| Vehicle | ECU | Power | Torque |
|---|---|---|---|
| Volkswagen Golf Mk8 2.0 TSI GTI · Petrol | Bosch MG1CS001 | 245 → 300 hp +55 | 370 → 440 Nm +70 |
| Volkswagen Tiguan 2.0 TDI DSG 4Motion · Diesel | Bosch EDC17C74 | 200 → 245 hp +45 | 400 → 470 Nm +70 |
| Audi A4 B9 40 TFSI S tronic · Petrol | Bosch MG1CS011 | 204 → 250 hp +46 | 320 → 410 Nm +90 |
| Audi Q5 45 TFSI quattro · Petrol | Bosch MG1CS011 | 245 → 295 hp +50 | 370 → 450 Nm +80 |
| BMW 320d G20 2.0d Steptronic · Diesel | Bosch EDC17C76 | 190 → 230 hp +40 | 400 → 460 Nm +60 |
| BMW 330i G20 2.0i Steptronic · Petrol | Bosch MG1CS003 | 258 → 315 hp +57 | 400 → 480 Nm +80 |
| Skoda Octavia Mk4 2.0 TDI DSG · Diesel | Bosch EDC17C74 | 150 → 195 hp +45 | 360 → 420 Nm +60 |
| Skoda Octavia Mk4 2.0 TSI RS · Petrol | Bosch MG1CS001 | 245 → 300 hp +55 | 370 → 440 Nm +70 |
Where these numbers come from
Every figure is drawn from our own vehicle catalogue, built from the calibrations we actually ship rather than from generic percentages. That is why the numbers differ between two variants that share a model name: a 2.0 TDI in one generation runs a different control unit, a different turbo and a different factory torque limiter from the next.
The gain shown is always the difference between the stock output and the tuned output for that specific variant. Nothing is rounded up for effect, and the stock figure is the manufacturer's own.
What affects the result on your car
A calibration works with the hardware in front of it. Two cars of the same variant can land on slightly different numbers depending on condition, fuel quality and what has been fitted, which is why these are typical results rather than a guarantee.
- Engine and turbo condition, and how recently it was serviced
- Fuel grade — higher octane gives a petrol calibration more room
- Supporting hardware such as intake, exhaust or intercooler
- Ambient temperature and altitude on the day
- Gearbox type, particularly on torque-limited automatics
Stage 1, Stage 2 and Stage 3
Stage 1 assumes an otherwise standard car and is the figure shown by default — it is the safe, everyday option and the one most customers buy. Stage 2 expects supporting hardware, typically an exhaust or intake upgrade. Stage 3 is matched to a specific modified build and is quoted per car rather than from a table.
