Hello everyone, I am fairly new to the car tuning scene and I'm full of questions.

I have a project that I'm acquiring knowledge for, so here is my question.

I have a w204 c220d mercedes and i want to tune the stock ecu with WinOLS what I find in the maps are stock values for example max torque request, max RPM, max air pressure etc.. are already defined in those axis of the maps. If I go for a bigger turbo I will have an increased air pressure and flow also I will have more requested torque, so how can I add those new undefined areas to the map of the ECU?

With my current knowledge I can think of editing the axis to have a higher value. For example instead of having the max rpm value be 4900rpm I will have to edit the axis of the map to 6000rpm while maintaining a 16x16 map same size but different axis values. Does this make sense? Will this create problems?

Thank you for reading my post, I hope that you could help me find some answers.
