Another tuning company that doesn't show the data necessary to judge whether the tune is safe or not — namely, an AFR chart.

With turbos, it's very simple to get more power — just add boost! But, unless you also add some fueling to mitigate detonation, the results can be disastrous!
What exactly would an AFR chart tell you?

And what would you need to look for to determine if the tune is safe? I would even know where to start mate
It would tell you whether, as the result of the tuning box or tune, the ratio of air to fuel in the mixture was too lean. Which is what causes detonation. Yes, it's a subject in itself worth researching. But if a tuning box does not appear to connect to the car's sensors, then it is likely the additional power is being achieved through adding boost alone, without compensatory fueling....which can lead to a very ugly "BANG"!

That's why I like to check if tuning companies are providing a full set of data, to see if they are safe. If not, then — personally — I stay well away from that company.
