Custom Calibration

NOT EVERY BUILD
FITS AN OFF-THE-SHELF MAP.

Modified vehicles can require calibration tailored around the actual hardware, fuel and intended use. Custom-map options are available for suitable applications when an off-the-shelf calibration isn't the right fit.

Send us the full specification of the vehicle and we'll advise on the most appropriate tuning route before anything is booked.

Before You Book

COMMON
QUESTIONS.

Not sure what map or supporting hardware you need? Send us your vehicle details and we'll help you work it out.

WhatsApp Us →
Do you only tune BMWs?
No. BMW is our specialist area and is where we offer Bootmod3 and xHP, but ECU remapping is available for a wide range of other makes and models subject to vehicle and ECU support.
Are you an authorised Bootmod3 and xHP installer?
Yes. DC Prestige is an authorised dealer and installer for Bootmod3 and xHP Flashtool, allowing us to supply the software and install supported BMW tuning packages through our workshop.
Can you provide a custom map?
Custom calibration options are available for suitable vehicles and builds. Send us the full vehicle specification, modifications, fuel used and intended use so we can advise on the appropriate route.
Do I need supporting modifications?
It depends on the vehicle, tuning level and intended use. Some software packages work with standard hardware, while others are designed around upgraded intake, exhaust or cooling components. We'll advise before the work is agreed.
Can you supply and fit the performance parts too?
Yes. We can supply and fit supporting upgrades including intakes, downpipes, charge pipes, charge coolers, intercoolers, exhaust components and other suitable performance hardware.
Will tuning affect my warranty or road legality?
Performance software or hardware can affect manufacturer warranty, emissions compliance and road legality depending on the modification. Some parts or calibrations may be intended for competition or off-road use only. We can discuss the relevant considerations before work begins.
What do you need to quote me?
Send your registration, vehicle and engine details, current modifications and what you want from the car. If you aren't sure what stage or software you need, that's fine — we'll advise.
