Custom remaps — pops & bangs, launch, limiters and more
Want more than a standard Stage 1? We build custom files around how you use the car: crackle and pops on the overrun, launch control, raised rev limits, start-stop off, or a speed limiter set where you need it.

Custom remaps
A file built around you
Two owners of the same car rarely want the same thing. One wants a quiet, torquey daily driver; the other wants it to crackle on the overrun at a show. A custom remap is written to your list, not a menu someone else decided.
Common requests are pops and bangs (burble on the overrun), launch control, raised or removed speed limiters on vehicles where that is lawful, start-stop disabled by default, cold-start noise reduction, and torque-limiter changes for modified gearboxes.
We talk through every option before we write anything — including the ones we would advise against. Overrun maps, for example, add heat and wear to the exhaust and catalyst, and are best kept mild on a daily driver.

Questions
Custom remaps — your questions answered
Are pops and bangs bad for my car?
Mild overrun maps are fine on most cars, but aggressive ones add heat and wear to the exhaust and catalyst. We keep daily drivers mild and explain the trade-off before we write anything.
Is it legal to remove a speed limiter?
On private cars, raising a manufacturer limiter is generally lawful. On vehicles that are legally required to have a limiter — some goods vehicles and buses — it is not, and we will not remove it.
Can you add launch control to any car?
Only on ECUs that support it. We check your exact ECU before you book.
Do I need Stage 2 hardware for a custom file?
No. Custom options can be added to a Stage 1 file. Stage 2 is only needed for higher power targets.
Can you undo it later?
Yes. The original file is saved and can be written back.
