Car Stage 1 + Pops & Bangs

Turn heads and unlock hidden power with the gdm Tuning Stage 1 + Pop & Bang Package — combining our professional Stage 1 ECU remap with a Crackle Map tune in a single mobile visit, saving you £99 versus booking each service separately.

Our Stage 1 remap optimises your engine's fuelling, ignition timing, and boost pressure — delivering noticeable gains in power, torque, and fuel efficiency, all without any hardware modifications. The Pop & Bang Crackle Map adds an aggressive exhaust note on overrun, with pops and crackles on gear changes and throttle lift-off — the perfect finishing touch for drivers who want performance they can hear as well as feel.

• Increased BHP and torque from Stage 1 remap
• Improved throttle response
• Better fuel economy
• Aggressive pops and crackles on overrun and gear changes
• No hardware modifications required
• Both services completed in a single mobile visit
• Fully reversible on request

Suitable for petrol cars. Contact us to confirm compatibility with your make and model before booking.

Service Area

This service is currently available to customers in the following postcode areas only: NE, SR, TS, DH, DL, TW. If your postcode does not begin with one of these prefixes, we are unable to offer this service at this time.

Once your order has been placed, a member of our team will be in touch to arrange a convenient fitting appointment. Whilst every effort is made to complete your remap as soon as possible, during busy periods there may be a wait of up to 2 weeks.

Performance Gains & Expectations

Any quoted performance gains are estimated figures only and will vary from vehicle to vehicle depending on the condition, wear and tear of the engine and associated components. The remap will be carried out to achieve the best of each vehicle's individual capabilities, within safe factory parameters.

gdm Tuning cannot be held responsible for unrealistic expectations. Whilst customers may have an idea of how they would like their vehicle to perform, it is not possible to tailor a remap to an exact customer specification. Results will always reflect what the vehicle is safely and mechanically capable of delivering.

Terms & Conditions — Please Read Before Booking

Elective Service & Limitation of Liability

ECU remapping is an elective modification chosen entirely at the customer's discretion. By purchasing this service, the customer acknowledges and agrees that:

• gdm Tuning accepts no responsibility whatsoever for any damage, failure, or deterioration of the vehicle, its engine, drivetrain, or any associated components arising from or connected to the remapping service.
• The customer proceeds entirely at their own risk.
• It is the customer's sole responsibility to ensure their vehicle is in a suitable condition to receive a remap prior to booking.
• gdm Tuning strongly recommends that the vehicle is serviced and mechanically sound before any remapping work is carried out.

No Refund Once Service Completed

Once the ECU remap has been carried out, the full service charge becomes non-refundable, regardless of whether the customer is satisfied with the outcome. By purchasing this service, the customer acknowledges that the remap is an elective modification performed to the best of the vehicle's mechanical ability, and that dissatisfaction with the results does not constitute grounds for a refund. This is in accordance with the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, which provides that the right to cancel is lost once a service has been fully performed with the customer's prior agreement.

Vehicle Condition

By completing this purchase, the customer confirms and warrants that their vehicle is in a suitable mechanical condition for remapping. If, upon inspection at the appointment, the vehicle is found to have pre-existing faults or visible issues — including but not limited to boost pipe leaks, air leaks, fault codes, or other mechanical defects — gdm Tuning reserves the right to decline to carry out the remap and retain a £99.00 attendance and assessment fee. The remaining balance will be refunded.

Cancellation Policy

Cancellations must be made at least 24 hours before the scheduled appointment. Late cancellations or no-shows will incur a £99.00 cancellation fee, in accordance with the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.
