Stage 2 tuning files for supported hardware setups.
Stage 2 tuning files for tuners who need the file matched to turbo, intake, exhaust, cooling and supporting hardware notes before delivery.
Stage 2 file intake
Stage 2 converts when the page makes the buyer send hardware details first, because the wrong file on the wrong setup creates revisions.
Best-fit buyer
Best fit for vehicles with downpipe, intake, intercooler, turbo or other supporting modifications already fitted.
It protects margin because the quote starts from the real setup, not from a vague tuning stage name.
File check
The file check needs the exact hardware list, ECU HW/SW, existing file state, fault codes and fuel target.

Frequently asked questions
What is the difference between Stage 1 and Stage 2?
Stage 2 requires hardware modifications such as downpipe, intake or intercooler. The ECU file is calibrated to match the upgraded hardware for higher gains.
Do I need to send my hardware list before ordering Stage 2?
Yes. Stage 2 files must match the exact hardware setup. Send the full modification list, ECU HW/SW numbers and current file state before work begins.
Can ACE build a Stage 2 file if another tuner made the Stage 1?
Yes, but ACE needs to inspect the current file state first. Send the file and the known modification history so the Stage 2 build starts from the correct baseline.
What does a Stage 2 file cost?
Stage 2 files start at 49 euros. The final price depends on the scope of hardware modifications and required calibration work.
