BMW is our home. From N47 to B58.

Most cars on our lift are BMW. Diagnosis with ISTA, maintenance by BMW schedule, and we know the common weak spots by sound. Other brands? Just as welcome, same mechanics.

One lift, from Stage 3 to oil change.

Chiptuning is our craft, but the same mechanics handle your MOT, maintenance, tyres and aircon. One number, one invoice, fair price. Saves you three appointments and two drop-offs.

How it works

In this morning, out this afternoon.

Four steps, no hidden costs. Before/after dyno measurement, certificate in hand, warranty on paper. If we have doubts we'll tell you honestly that your car doesn't need tuning. Rather one customer less than a damaged reputation.

  1. 01

    Plate

    Enter your plate and see gain per stage and indicative price on screen in 10 seconds.

  2. 02

    Diagnosis

    We read the OBD and inspect the engine on the lift. Only then a definitive go or an honest no.

  3. 03

    Dyno

    Power before. Software on. Power after. All on our own dyno, no estimated figures.

  4. 04

    Certificate

    Dyno chart, certificate in your name and 5-year software warranty in writing. Keep it alongside your registration.

Why ASF

No sales talk,no blue suits,just our own dyno.

Independent, not a tuning shop with a logo and a TikTok account. 2,400+ cars tuned on our own dyno. 5-year warranty on our software, in writing. If your car doesn't fit, we'll say so. Rather one customer less than a damaged name.

    Maandag binnen gegaan, dinsdag auto afgezet, woensdag auto terug en tip top in orde. Heb een hertune laten doen en sta er echt van versteld wat ze er nog uit hebben kunnen halen. Ik weet waar ik ga voor mijn auto.

    Ik ben in veel garages in München geweest, maar niemand kon mijn probleem vinden of oplossen. Toen ging ik naar ASF Performance in Nederland — en daar hebben ze het probleem binnen een half uur gevonden en opgelost. Eerlijk gezegd, dit zijn de beste mensen voor luxe auto’s. Super service, veel kennis en heel vriendelijk. Echt een aanrader!

    Mooi en goed bedrijf. Heb net mijn auto laten tunen, echt een groot verschil. Goede communicatie en toffe gozer. Goede uitleg. Aanrader voor iedereen die zijn wagen wil tunen.

    ASF Performance heeft mijn Audi RS6 getuned en het resultaat is echt top. Ze luisteren goed naar je wensen en stemmen de tuning perfect af op jouw rijstijl en voorkeuren. Super service, vakkundig en klantvriendelijk.
