Mobile tuners and those acting as agents for other tuners are nothing more than resellers—they are not true tuners.
What does this mean?
These individuals simply install files created by someone else, with no real understanding of what’s being changed in your ECU. If they truly had the skills and expertise to tune a vehicle themselves, they wouldn’t need to rely on another company’s work.
Common concerns with mobile and agent tuners:
- Why don't they have a workshop? Proper tuning requires controlled conditions, specialized equipment, and a dyno—not just a laptop in a car park.
- What happens when something goes wrong? If a file is bad or causes issues, these tuners rarely have the knowledge to diagnose or fix it. Instead, they rely on their "supplier" to send another generic file.
- They have no real tuning experience. Many mobile and agent tuners are just middlemen with limited mechanical knowledge, selling files they don’t understand.
- No genuine custom tuning. A mobile tuner or agent cannot develop a tune specifically for your vehicle. Instead, they load a pre-made file from whoever their tool is slaved to.
- They do this because they lack the skills. If they had the knowledge and ability, they would be writing their own tunes—not reselling someone else’s.
