Proving that a tuning box is no comparison to mapping, the difference in the graph looks like a stage 1 car v standard car when in fact this was running a very expensive 7 channel tuning box, this was tested in its most "aggressive" mode and was nothing like he was led to believe.
Proving time and time again that mapping and tuning boxes cannot be compared.
