Who writes this

Built by someone still turning spanners

Metro Torque & Tune is written and maintained by Harlin David Orozco Araujo. Every guide here is original, written in plain English, and checked against how the jobs actually go on the bench — including the safety steps it is tempting to skip.

The aim is simple: explain things clearly enough that you understand why, not just what. We earn nothing from sending you elsewhere, and we always tell you when a job is better left to a professional.
