Eco chiptuning is almost the same as a preformance chip tuning. With preformance, there is ovet the hole rpm range more power and torque. With the eco chip, there wil be in lower rpms only a torque and power raise. In high rpm it will be still the same as factory. If you have non turbo cars. If you chip it, there will be verry low to no gain. With turbo cars the gains are much higher. I went from 136hp and 310nm (turbodiesel car) to 200hp and 400nm with a chip and bigger intercooler. Used the preformance chip on a dyna handmade. Not the eco chip.

Gains in milage was 0.5l /100km.
