Diagnostic Connections Limited T/A DC Tuning and/or any Authorised DC Tuning Agent shall provide vehicle tuning services requested by the client from the following options, all of which are bound by our customer care and commitment to service quality.

The tuning files that we install will never change. So when we complete our tuning service on your vehicle it will continue to perform at the same capacity it did on arrival or show improvements from our tuning files. Once tuned, we are confident that tuning services provided which are based on the optimal settings that are most suitable for you vehicle and should produce noticeable benefits. Following our work, if an issue arises with your vehicle it will most likely be due to a mechanical fault, not a fault with the tuning file itself. Once the mechanical fault is fixed your vehicle should revert to its optimum performance.

All vehicles presented to DC Tuning and/or any Authorised DC Tuning Agent will be deemed fit upon presentation and it is not the responsibility of DC Tuning and/or any Authorised DC Tuning Agent to prove this. It is the responsibility of the customer to ensure that the vehicle is up to date in respect of servicing and all mechanical and non-mechanical parts as per the manufacturer schedules. Any unforeseen damage that may occur during or after the tuning process is not covered or guarantedd by DC Tuning and/or any Authorised DC Tuning Agent. DC Tuning and/or any Authorised DC Tuning Agent will advice the customer of any faults that become apparent during or after the tuning process. We will not accept any liability from the date that the tuning process was carried out. If oyu have carried out and modifications to you vehicle and your vehicle subsequently develops a fault, we will not accept liability for any of those parts before, during or after any tuning process.

A vehicle diagnostic health check showing any fault codes will be carried out before and tuning work is undertaken, and we reserve the right to refuse any vehicle that we believe to not be “healthy” enough. No warranty is given or implied to any components on your vehicle before or after the tuning process apart from the tuning file itself. Refunds are not accepted. DC Tuning and/or any Authorised DC Tuning Agent do not accept liability for any mechanical part failure after performance tuning. By using our service, you agree to these terms and conditions.

It is most important to remember that vehicle components can fail when standard just like the can when a vehicle has received a tuning file. Tuning will often show up any weak points in your vehicle as you are asking it to work harder that it has been used to. You must look after the engine with regular servicing with good quality oil and parts, good quality fuel and mechanical sympathy all help to keep your engine running well. If your car needs mechanical attention, get this work done before considering a tuning file.

DC Tuning and/or any Authorised DC Tuning Agent do not cover the liability for any mechanical or electrical parts including the following: Turbos, injectors, clutches, gearboxes, DPF, boost leaks (boost pipes) as these have a serviceable lifetime and the tune places higher demands on these parts, which may cause issues if they are not in good health. If Economy, Stage 1, Stage 2 and Stage 3 tunes are beyond the recommended tolerances of your engine then DC Tuning and/or any Authorised DC Tuning Agent will not accept any liability for the tuned files. We work alongside external “file writers” and the liability for any mistake in the modified files and we work closely with them to rectify any tuning files issues immediately.
