My Passat GLX has a speed cut-off around 130mph. I asked the dealer in Turkey, if I can remove that cut-off and I was told that they can only decrease the speed limit, and that I have to get a new ECU for removing it.
This 2.8litre engine is using more gas than anyone else on the road, and I can not even enjoy it due to this limit. I have to move aside for even a 170hp Mercedes C200 Kompressor (2litre engine with compressor). I looking for a chip that will either decrease the gas consumption (I am OK to give up some horsepower) or remove this speed limit. How much would that cost, and how easy is it to install? Would it do any harm to my engine?
PS: I wish it had the technology to turn off some cylinders at low RPMs... The gas is $6 a gallon here!!!
