Trusted Van Specialists – Kent & East Sussex
At RubyTune, we specialise in safe, proven ECU remapping for vans and light commercial vehicles, delivering genuine improvements in performance, drivability, and everyday usability — without compromising reliability.
We’re a Trading Standards Approved, family-run business, led by an IMI-Certified Installation Engineer, with 350+ genuine 5-star reviews from customers throughout the South East.
Unlike “upload-and-disappear” tuning companies, every commercial vehicle we remap is first assessed using live diagnostic testing to ensure it’s mechanically suitable for calibration — because real results only come from healthy engines.
✅ Real-World Benefits for Your Van
A professionally calibrated remap can transform how a working vehicle drives day-to-day:
• Stronger torque for easier towing and loaded driving
• Reduced gear changes and smoother power delivery
• More responsive throttle and better mid-range pull
• More relaxed motorway cruising
• Improved drivability in traffic and on hills
No exaggerated figures or sales hype — just honest working-vehicle improvements that make your van easier and more enjoyable to drive.
🔍 Why RubyTune Does It Differently
Many tuning companies simply upload a generic file and leave.
At RubyTune, we diagnose first — tune second.
Every vehicle goes through our steady-state live data health check before any remap is installed, including:
• Injector balance verification
• Airflow (MAF) plausibility testing
• Boost control monitoring
• Fuel trim checks
• EGR operation validation
• Diesel DPF loading assessment
If anything isn’t right — we stop the process and advise you honestly.
That’s how we protect your engine, turbo, gearbox and emissions systems while still delivering meaningful performance improvements.
No exaggerated figures or sales hype — just honest working-vehicle improvements that make your van easier and more enjoyable to drive.

I would highly recommend using RubyTune, Andy turned up on time and was very professional throughout. Over the moon with the upgrade and can really tell the difference.
Just had my Transit Custom and BMW X3 remapped very impressed excellent service thanks Andy great job
This van is sooooo much better!
These lads remapped my van this morning…proper job…it’s a weapon now …cheers.
Very impressed! Andy was punctual, knowledgeable and professional, he listened to what I was looking to achieve from my Ford Transit and then met those requirements. I am very pleased with the results, I have noticed a real improvement when towing and am also seeing an improvement in the Economy.
The difference is night and day, thankyou!
Removed speed limit from my van and added extra power. Fair price for quality service.
Thank you again Andy
Andy’s a great guy, made such a difference to our struggling Connect. Wouldn’t go anywhere else, highly recommend.
