With the S5’s they tend to suffer with carbon build up meaning they’re under powered as standard, we would start with a health check on the dyno to see what and how your car is performing, then proceed with removing your manifold, walnut blasting and removing the carbon build up, we would replace your air filter with a BMC high flow filter, and then tune your car back up to what it should be running as standard, even though you’re going up to stock figures, because the car is under powered you will notice a big difference!

We would require your car to be dropped off and left with us for 3-5 working days to carry out the work. We would require an initial deposit of £150 to secure your booking.

Please make sure your car arrives with at least half a tank of fuel and is always run on the best fuel, which in the UK is Tesco 99 Momentum.

Please be aware that old coilpacks can fail when running more power, causing a misfire, please make sure you have newest revision coilpacks before booking in, or let us know and we can add these to the estimate and replace on the day.

Please make sure that you mention all work you’re wanting to be carried out before booking in so that we can schedule this into the diary accordingly.

Mentioning work when you drop your car off means that we will run into delays as it was not scheduled in the dairy.

Injectors are becoming a common issue on the 8P and 8V.1 models, we do recommend having them removed and replaced for the latest revision. We do also offer testing and cleaning. When checking and cleaning Injectors they should always be flow matched to be within 1% of each other, depending on your results will depend on if we can re-use or if we have to replace them. If you would like this to be priced up, please let us know so we can adjust your estimate to suit – for more information about injector cleaning click here.
