Level one
Stage 1
No hardware changes, no compromises. A Stage 1 file unlocks the headroom your manufacturer left on the table for global tolerances you'll never see.
Typical gains
What to expect
Figures are typical ranges from our own road-logged data. Your exact result depends on engine condition, fuel grade and ambient conditions. We quote a specific figure before you commit.

Good to know
Stage 1 is right for you if…
If any of these don't apply, talk to us first. We'd rather turn work away than write a file onto a tired engine.
Your car is standard
Factory airbox, exhaust and intercooler still fitted.
Servicing is up to date
Fresh oil, filters and, on petrol, healthy spark plugs.
No live faults
Nothing stored that points to boost leaks, injectors or a tired clutch.
