Title says it all.
Living in Europe corresponds to high gas prices, so i was wondering if an ECU remapping might save some money in the long term. Also… are there any negative impacts on the engine or other parts that should be put in consideration?
Factory tunes need to compile with emissions regulations so with custom tune which doesn’t compile with them you might save some amount of fuel. Basically it’s illegal but there isn’t really a way to test for example NOx easily, that’s why it took so long to catch vw with dieselgate.
