Hi,
first of all could you kindly provide more information about your car and about the planned tuning?
It is possible to "stage" the performance.
for example F30 LCI 320D Factory power 190PS (140KW)
Eco -> 190 PS
Comfort -> 200 PS
Sport -> 225 PS
Sport+ -> Safe max limit
I would suggest you a ECU remap ( i guess you drive a 320D 2012)
