What I highlighted is the fact of performance, what goes in has to equally be able to come out.
Also, you have to keep in mind as a consumer if a chip/hand held tuner alters the factory tune it will show up when the computer is flashed and you can pretty much kiss any warranty you have good bye on newer vehicles.
I've seen diesel engines with chips to have premature head gasket failure due to the increased boost.
