We’ve had a short break to recharge the battery, however file service never stopped so our dealer network that’s world wide could continue to work showing our commitment to our network.

We will also update on jobs done in the workshop before our break and reply to all messages asap.
Thanks SLT

Nice early start with our file service 👌

At SLT, we don’t use automated file services like so many others in the industry these days, where it’s a “one size fits all” approach.

That’s not how we work. Not every vehicle is the same — especially higher mileage vehicles.

With our hands-on human file service, we take every bit of information into consideration when a file is sent to us for tuning or deletes. Yes, it may take a little longer, but care and attention always do 😉

If you want a real human file service and not just a program firing files back automatically, feel free to register below:

We’ve recently seen a growing number of DQ381 / DQ500 Medtronics units coming through our doors that have already been “repaired” elsewhere… and honestly, the workmanship has been shocking.

From low-quality replacement parts to extremely poor soldering, the standard we’re seeing is well below what it should be. The photos really speak for themselves.

✅ Fast 2-day turnaround
✅ High-quality components
✅ Professional, reliable workmanship

We’ve designed this to be a smooth and efficient process from start to finish.

🔧 Volkswagen Scirocco R – Custom Remap Development

This Scirocco R (Diesel) came in for tuning, but it quickly became clear this wasn’t a straightforward job.

After initial testing, we discovered the vehicle had already been tuned previously — unknown to the customer. The car felt extremely flat low down, only really coming alive around 3400rpm, where it would suddenly spike to ~2 bar of boost.

📊 Diagnostics & Investigation
• Data logs confirmed 2 bar boost pressure
• No fault codes present
• No obvious mechanical issues on inspection

Despite everything looking “normal” on paper, the car’s driveability was far from right.



🔄 Back to Stock

After discussing with the customer, we made the decision to return the vehicle back to stock software.

Immediately, we saw:
• ✅ Restoration of low-down power
• ✅ Much smoother delivery
• ✅ Clean, consistent logs

Although still slightly down on performance, this confirmed the issue was entirely software-related from the previous tune.



⚙️ Safe & Correct Calibration

Given the car had been running poorly for some time (known the exact time has customer only owned the vehicle 3 weeks), we took a measured approach to the new calibration.

Rather than chasing figures, the focus was:
• Smooth, progressive power delivery
• Strong performance across the full rev range
• Maintaining engine safety and reliability



🚀 Final Result

The result is a properly calibrated Scirocco R that now drives exactly as it should:
• Linear power delivery
• No aggressive boost spikes
• Consistent and predictable performance

A great example of why correct tuning matters just as much as peak numbers.
