A Stage 1 diesel remap in Europe ranges from €80 to €600+ depending on country, reputation, and differentiation.
What drives the higher end: The calibrator can explain what they changed, offers logging data, has visible past work, and specializes.
The specialist premium: Calibrators who work on marine engines, agricultural equipment, or exotic cars face almost zero price competition.
My observation: Most calibrators price below what the market would accept if they had better evidence of their expertise.
Build the capability first, then document it. The pricing follows.
Diesel Practice builds that capability — including the documentation habits that justify premium rates.
