Question 1

Is chiptuning bad for my engine?

Accepted Answer

Not if the software is right. We stay within the factory margins of the block, injection and turbo. On our dyno you see before/after that the values are safe. That's why we dare give a 5-year software warranty. Damage from our software? We pay the repair.

Question 2

What if I don't notice the extra hp?

Accepted Answer

We measure before and after on our own dyno. If the gain isn't on paper, we keep tuning until it is, at no cost. 2,400+ tunes and never needed, but the deal stands.

Question 3

What happens to my factory warranty?

Accepted Answer

The factory powertrain warranty lapses on tuned parts, that's the legal position. That's why we give a 5-year warranty on the software ourselves. Parts outside the powertrain (aircon, electronics outside the ECU) keep their factory warranty.

Question 4

Will I have issues with the MOT?

Accepted Answer

No. We stay within the Euro standard your car complies with. DPF, EGR and AdBlue keep working as required. If in doubt, we do the MOT in the same appointment.

Question 5

And my insurance?

Accepted Answer

Some insurers want to know about power changes. You'll get the dyno report and certificate to declare it cleanly. A correct Stage 1 rarely changes premiums.

Question 6

Can the tuning be reversed?

Accepted Answer

Yes. We always keep the original file, so we can return your car to factory at any time.

Question 7

How long will my car be away?

Accepted Answer

Stage 1 software-only: 3 to 4 hours including dyno before/after. Stage 2 with downpipe: one day. Stage 3 depends on hardware choices — we'll plan ahead so you're not without a car.

Question 8

What does it cost exactly?

Accepted Answer

Stage 1 from €350, including before/after dyno, certificate and 5-year software warranty. Stage 2 from €899. Stage 3 on request. Email your plate to info@asf-performance.nl, we usually reply within 1 day.
