Chiptuning is also called ecu programming or obdtuning.
With a chiptuning you get between 15 - 60% more hp,
more torque and up to 25% longer per liter
Turbo cars achieve up to 25-60% extra hp
However, it is always your own responsibility if your
car can withstand the extra hp due to age etc.
The number of hp in addition to the 35-40%
depends on the tuning parts that are retrofitted.
