The factory tunes for the whole world.
We tune for you.
Factory calibration plays it safe for every market's fuel, climate and emissions rules. Your engine has been holding back this whole time. The right tune with the right hardware takes that power back. Every car is road-tested and has to hit its datalog targets before handover.

"I want this thing to fly."
2025 Focus ST Wagon · Owner: Chih · stock straight to Stage 2
Fifteen months into ownership, he walked in worried about the factory warranty. His last words were "modding takes guts". Then he went all in: downpipe, turbo hoses, intercooler and a Stage 2 tune in one hit. After delivery, he stuck the #AS decal on the tailgate himself.

Some jobs, we turn down.
We don't tune a car that isn't healthy. Fix it first, then talk power. Upgrading in stages never costs you twice: everything you fit now carries straight over to the next step. We take the time to understand how you drive, then give it to you straight.
