G.A.P.

Hi i would like to improve the power of my MB GLC 220 D and someone sells a tune obd module that offer the possibility to tune the control motor unit improving power up from 170 HP/420 HM to 232 HP /500 HM ..The module seems to act in only few minutes moreover you can back to the original dealer firmware with the same devices, likely no affecting warranty, no wire, no ECU open, no soldering just plug and play. Is there anyone that can offer me further information about this topic? Thanks a lot.
