Don’t compete on the same axis. The €50 vendor sells a file. You sell a result.
Reframe the conversation:
“A generic file is built for the average car. I’m calibrating to your car.”
“The €50 option gives you no accountability. I stand behind what I build.”
“I log your car before and after. The vendor doesn’t know your car exists.”
The clients who value accountability are worth having. The ones who want €50 files — let them go.
Building the expertise that justifies premium pricing is what Diesel Practice is for — you learn to create calibrations you can explain and defend.
