Compare the numbers.
Keep the context.
Enter a baseline and proposed or measured figures in the same unit. See the power and torque difference. This calculator does not predict gains or check vehicle support.
Add your figures to begin.
Use your own source figures. No default percentage or vehicle prediction is applied.

A mathematical difference is not a tuning prediction.
The comparison uses only the numbers you supply. It cannot establish support, condition, achievable output or safe limits. Estimates remain estimates, and a measured figure still needs its source and test conditions. Engine figures should be compared with engine figures, and wheel figures with wheel figures.
The calculation is comparison minus baseline; the percentage is that difference divided by the baseline, multiplied by 100. A lower comparison gives a negative result, and equal figures give zero. Both power entries retain the unit you selected.
Read the guide to power units and measurement basis or understanding a complete dyno graph. For an actual tuning quote, send the vehicle specification, fuel, hardware, gearbox and postcode.
