Frequently Asked Questions
How much power will I gain from a Stage 1 remap?+
Typical Stage 1 gains range from 20–40% BHP and torque depending on your engine and factory tune. We'll confirm exact expected gains for your vehicle before booking.
Is a remap safe for my engine?+
Yes — when written by qualified tuners using tested files. We only calibrate within safe factory hardware limits and verify with live logs before handover.
Will a remap void my manufacturer warranty?+
Any ECU modification can affect warranty coverage. If your vehicle is still under manufacturer warranty we recommend discussing it with your dealer first.
Is the remap reversible?+
Yes. We back up your original ECU file before any changes so the vehicle can be returned to stock at any time.
How long does a remap take?+
Most OBD Stage 1 remaps take 45–90 minutes. Bench and boot-mode flashes take longer — we'll confirm the exact duration when you book.
Will fuel economy improve?+
Diesel remaps typically improve MPG when driven normally. Petrol tunes are performance-focused, so economy depends on driving style.
