Being a man means trying to extract all of the performance potential out of our engines in the stealthiest way possible and getting away with it.
Are you that na´ve to think that they have no way to tell that it's been "tuned?" Ha Ha Ha. Let's see. There is a maximum spec for boost pressure, turbine speed, turbine outlet temperature, NOx output, fuel consumption rate...... any one of those could be used as in indicator. I see it all the time as I work for a engine mfg of class 8 truck engines, some of which people "tune". We've been wise to that for at least a decade. We have failure analysis guys that are specifically trained to look for the signs. Now mfgs of automotive diesels are getting wise to it as well. As I said, the scrutiny my buddy's 6.7 was subjected to before Ram/Cummins honored the warranty claim was nothing less than amazing. Even though all the ECM tattletale indicators were in spec (because he never tuned it), the factory engineers STILL had the failed parts shipped to them and analyzed carefully before allowing the dealership to do anything. It took like four weeks to work thru it all. Thank goodness he had never tuned it or he would have been hosed big time.
Yep. Tuning stuff is cool. Man's genetic make-up means we get off on horsepower, fossil fuels, and speed. But blowing something up then lying about it to try to get somebody else to pay for it is not cool. Major man code violation if you ask me. You should know this!
