MRC Tuning Ltd is a remapping/tuning company:
We tune all post 1998, drive by wire, VAG/Porsche and a select few other brands with Bosch/Siemens ECUs.
Please read and understand our “responsible tuning policy” before undertaking any tuning work
There is a comprehensive FAQ and instructions on modifying your car that should be read and understood before modifying and bringing your car to be tuned. This is available in the reception.
We cannot warranty any engine. We can guarantee our remaps will be safe at the time the car is mapped.
If you are not happy in any way with the remap we will refund the remap cost within 14 days of the remap.
We cannot quote any leadtimes for non OE work or modifications to cars. All project or custom work will not have any defined leadtimes or completion dates. We will only give expected time for the labour of work.
Running a car on the dyno is at the customers own risk.
Any test drives by MRC Tuning Staff are at the customers risk. Our staff are insured to drive customer cars.
We charge £22+vat per day for storage of cars, which will take affect after 2 weeks of the booking in date, or after 1 week of completion of work.
All cars must be taxed, have the tax disc on display, insured and have a valid MOT at all times when on MRC Tuning property. We will not drive any cars unless they are known to be 100% legal for use on the road.
Cars will only be insured by MRC Tuning while work is being carried out inside the workshop.
There are no warranties on any modified cars.
For cars that require remedial work or modification prior to mapping we need to be informed of your budget as work may extend beyond initial estimates. We need this information before hand especially if the car is being left with us
In addition to remapping we can service/maintain/diagnose/modify/upgrade all post 1998 drive-by-wire VAG/Porsche cars at the owners request to their specifications. There are no warranties on any modified car parts fitted to a customers car.
Customer supplied parts:
When supplying your own parts for fitment please ensure they have been fully tested (with test results provided) and all fitting instructions are provided. The customer will have to cover costs any fitting issues or testing for parts we have not seen/tested/fitted previously. We cannot estimate gains or costs for parts we have not seen / fitted before.
We use VCDS, Durametric and VAG factory software for diagnostics.
All cars for diagnostics/remedial work should fill in a “diagnostic problem form” available in reception to help us identify the problem, when and how it occurs. The problem should be demonstrated to a member of staff. The form must be filled in to correctly identify and fix any issues.
Service schedules for modified (greater than 30% gain from stock) must be shortened accordingly. All engine oils and filters should be replaced on a 5k miles basis. Gearbox, diff oils and spark plugs should be replaced every 10k miles. Cambelt service should be carried out every 20k miles or less.
Cars with more than 50% incresase in power should have Health Checks every 4k. Oil and filters in gearbox and engine, spark plugs should be changed every 4k or after any track day.
All OE standard parts fitted to a modified car will not carry any manufacturers warranty or guarantee.
All modifications that differ from OE specifications, carried out by MRC Tuning are modified at the owners risk.
An Engine Health Check should be carried out every 6 months.
All cars should be test driven on the day of pickup to make sure any issues or problems have been resolved on the day of pick up.
MRC Tuning cannot test drive cars for prolonged periods of time. If the car has an intermittent issue the customer has to drive the car until the issue is testable by MRC Tuning.
We only use genuine parts for servicing and repairs unless otherwise stated or requested by the customer.
We request that all MAFs on cars are genuine VAG parts, due to aftermarket MAFs causing intermittent or regular failures. There is no warranty if the MAFs have been damaged by contaminates sprayed on them.
Running more power and torque through the drivetrain will always put more strain on parts.
You can have a failure on the first run after running more power or you can have failures years later. Please understand this and mechanical issues will not be warranted.
After tuning please drive your car for as long as possible before driving home in case you want anything changed or have any issues. We will always help out but if something is wrong and you carry on driving for days or weeks it can cause further issues.
To prevent and prepare your car for tuning there are some pre requisites you can make sure you have done or ask for a quote before tuning:
- Make sure your gearbox software is up to date. Especially on older cars or first run of cars there will be software updates. VAG have always had issues with gearboxes and update their software over time. Check with VAG before you come you have newest software.
- Service the gearbox, transfer box, diff and haldex. VAG will have a service schedule but you should reduce this at least by half and do a service before any tuning. Make sure VAG/other garages change all filters and seals and not just drop and change oil.
- We recommend the longer filling tube in DQ250 boxes to get more oil in and better cooling.
- Haldex without filters have to be flushed, the pump removed and mesh cleaned.
If you are not confident or worried about your car being reliable or parts wearing or failing then please do not ask us to tune your car. Please do not drive away without making sure you are happy with your car.
We use a service checklist for all service inspections. These are available for your car on request at time of picking up.
All cars booked in for service or diagnostics should be picked up within 1 week of the booking in date, or storage charges will be incurred.
MRC Tuning does not carry out any accident damage repair or bodywork.
We do have a car available on request. If you have requested a car please check it is available the day before you are due to drop off your car, as the cars can be returned late from previous bookings. You have to have full insurance cover for the use of a car from MRC Tuning.
By leaving your car at MRC Tuning, or having work undertaken by MRC Tuning, you agree to all the above terms and conditions.
