Company

A workshop first

Untd. Performance started in 2019 as a two-bay shop working on German turbo platforms. The catalogue exists because we got tired of ordering parts that did not fit and calibration files nobody would stand behind.

Everything we list has been fitted to a car in our own shop, or we say plainly that it has not. The dyno is ours, the numbers come off it, and the fitment desk is staffed by the people who do the installs.

What we stock, and why

Intakes, exhaust, charge cooling, turbo kits and calibration — the five systems that decide what a factory turbo engine can actually do. We do not carry cosmetic parts, and we do not carry a brand because it sells.

How we talk about power

Wheel horsepower, measured back to back on the same car on the same day. No crank estimates, no correction factor chosen to flatter the result. If a part underdelivered on a platform, the listing says so.
