Tunes can be safe, a 10psi tune is a lot for any car (based on what iDrive was showing which is a measured value if I'm not mistaken) I'd think a larger/better intake would be needed for proper air flow. Don't have any additional data showing the engineering parameters of the N63M engine in the G05?

Hey, thanks for the reply. Majority of increases whether a BMW, Ferrari, Mercedes, etc is 3.5-5.5 increase with boost tapering off towards redline mimicking the factory power band (no 10 psi increase on any stock platform. Cannot see what you are mentioning in I Drive but increase is not 10 psi)). Same holds true for the E70 chassis, F15, and now the G05 family. Regarding the parameters those are all within the tuning area of what is changed by our team. Majority is torque limiter, fuel, ignition control... Intakes are hit or miss , in our opinion the factory intake system is perfect.
