South Tuningz

South Tuningz was established at the beginning of 2020. The purpose behind South Tuningz was originally supposed to be a local mobile tuning service for people based in South London, that quickly changed to a service covering the Entirety of London, Cambridge, Oxford, Norfolk and Essex. From Brighton all the way too Dover and back towards Reading, Southampton, we have now opened a large workshop in Croydon due to the continued support from our great customers! Due to such high demand we have had to deeply invest in research & development regarding sophisticated professional tools and software providers that are regarded as some of the best software creators in the automotive industry. Through hard work, passion and a genuine love of all things fast the owner has built a mobile tuning company that prides itself on providing cutting edge software that has proven itself time and time again, five star customer services and attention to detail that very few can rival. The reason for all of this you ask ? The team at South Tuningz are very much against seeing genuine customers and members of the General public, falling foul of low quality generic remaps and bad customer service, unfortunately leaving people in compromising situations and generally giving tuning a bad reputation. The main goal for South Tuningz is too make the process of having your car tuned a fun, exciting & comfortable experience that leaves the customer feeling confident and content with the outcome of having South Tuningz work on their vehicle. We look forward to working with all future customers and helping anyone who may need our services.

🔥 AUDI RS6 — TRUE MULTIMAP ON THE FACTORY ECU 🔥

No DS1.
No plug-in adapters.
No aftermarket apps.
No messing around.

Apex Performance has set this RS6 up with multiple selectable maps directly on the FACTORY ECU — switchable on the go using the car’s existing controls, meaning you can switch between a low boost safe daily map into high boost or a rolling flame map at the press of a button whilst driving seamlessly on the rs platform!

And this video?
We’re showcasing MAP 3 — THE FLAME MAP 🔥🔥🔥

Turn the sound UP. 🔊
Would you daily this map? 😈

The impossible has officially been cracked! ⚡️🚀

No OBD dongles. No clunky phone apps. No pulling over to turn the ignition off. ❌
We have officially reverse-engineered the factory Audi C7/C7.5 RS6 & RS7 ECU code to bring you TRUE, LIVE multi-map switching directly from the cruise control stalk—at ANY speed, mid-drive! 🤯👇

Watch the rev needle drop to show exactly what map you’re in:
📍 1,000 RPM = Map 1 (Daily/Low Boost)
📍 2,000 RPM = Map 2 (High Boost)
📍 3,000 RPM = Map 3 (...the SURPRISE MAP you need to see on the dyno) 😉💥
We are putting this exact car on the dyno this week to showcase the live on-the-fly switching, and we’re letting Map 3 loose. Trust us, you do NOT want to miss this one. 👀👇

Drop a comment if your 4.0T V8 needs this setup!

BMW 335d xDrive in for some serious upgrades 👀🔥

✅ Darkside Developments manifold flap blank
✅ Custom Stage 1 ECU tuning
✅ xHP Stage 3 gearbox software
✅ Sharper shifts, stronger delivery & a completely different car

It’s now running great, but during tuning we found a slight underboost issue holding it back from its full potential.

Once that’s repaired, we can get it back in and push the Stage 1 setup towards around:

🚀 370–380 BHP
💪 750–800 NM

Not bad for a diesel daily… 😮‍💨

Would you leave it at Stage 1 or go further? 👀

🚨 BENTLEY CONTINENTAL 4.0 V8 BI-TURBO — BACK FROM THE DEAD 🚨

This EA824 Bentley came to Apex Performance Edenbridge after being sold “custom software” elsewhere…

The result?
❌ Barely 500HP
❌ No real power increase
❌ Huge flat spot
❌ Underboost issue
❌ Calibration looking more like someone button-bashing Mortal Kombat than properly tuning a V8 😭

We got it on the dyno, carried out full data logging and started again with our own custom engine + gearbox software.

Even WITH the underboost issue still present…

🔥 600+ BHP on our Stage 1 calibration 🔥

Next step:
🔧 Full inspection
🔧 Diagnose + repair the underboost
📈 Aim for 680–700+ BHP
👀 Maybe straight into our Stage 2 package…

This Bentley isn’t finished yet.

Want your car properly calibrated instead of just “mapped”?

MERCEDES-AMG GT63 S 4MATIC+ — THE DYNO SESSION THEY COULDN’T DO. 😮‍💨

This GT63 S came into **Apex Performance Edenbridge** already “tuned” elsewhere… but when we put it on our **4WD dyno**, it was effectively making stock power.

The previous tuner failed to successfully run the car on their 4WD dyno and the excuses started.

So we stepped in.

✅ Full 4WD dyno testing
✅ Multiple ECU revisions
✅ TCU calibration
✅ In-depth data logging
✅ Repeated power runs
✅ Proper testing from start to finish

We ran this absolute beast all day long, refining the calibration and extracting serious performance from our **Stage 1 ECU & TCU package**.

No guessing.
No excuses.
Just data, testing and results. 📈

And we’re not finished…

It’ll be back very soon for **CPC module tuning, spark plugs and our Stage 2 package**.

🎯 Next target: **800+BHP**

GT63 S owners… this is how these cars are supposed to be tuned.
