Is this a staged map or a custom tune for the Volkswagen Golf GTI?

Both. Our Staged maps are ready-made, off-the-shelf Stage 1 and Stage 2 calibrations you configure and flash yourself. Custom is a fully bespoke tune built around your exact hardware and fuel, with a revision loop and lifetime support.

Do you offer a Stage 1 map and a Stage 2 map for the Volkswagen Golf GTI?

Yes — Stage 1 (factory hardware) and Stage 2 (intake, intercooler, downpipe) are both configurable, in Staged or Custom form, for the 2.0T IS20.

Is this a remote tune or do I need a dyno?

100% remote, anywhere in the world. You flash the file at home with the eFlash dongle and we review your datalogs remotely — no shop visit and no dyno appointment.

What else is this called?

Depending on who you ask, an ECU tune is also called a remap, a Stage 1 / Stage 2 map, a staged tune, a performance map, a power map, a race tune, mapping or chiptuning. This is that product for the Volkswagen Golf GTI.
