I've recently come across a product, which has been mentioned in a few posts stating this Chiptuning from a german company with simple installation, can result in the above mentioned 56 HP and 120NM of power gain..
Has anyone tried this brand? Is this the cheapest Gain/$ out there?
Also states, sub 4 seconds 0-100km times.
