🔥 PORSCHE CAYENNE 3.6 GTS × JSV PERFORMANCE 🔥

440 HP ➜ 510 HP 🚀
600 Nm ➜ 730 Nm 💪

This Porsche Cayenne GTS came to us for the complete RaceChip performance package.

We installed:

⚡ RaceChip GTS Performance Module
⚡ RaceChip XLR Throttle Controller
⚡ GTS Running Setting 7

📈 THE RESULTS

Factory: 440 HP | 600 Nm

RaceChip GTS: 510 HP | 730 Nm

🔥 +70 HP
🔥 +130 Nm

That’s a serious increase from a plug-and-drive performance solution — with no ECU flashing required.

But power was only half of the upgrade…

We also installed the RaceChip XLR throttle controller, giving the Cayenne a much sharper and more immediate response from the accelerator.

The result?

⚡ More Power
⚡ More Torque
⚡ Sharper Throttle Response
⚡ Stronger Acceleration
⚡ Completely Different Driving Experience

💣 BIG NEWS FOR BMW & MINI OWNERS! 💣

Another major development from Magic Motorsport, and another upgrade to what we can offer at JSV Performance. 🔥

Selected BMW & MINI Bosch MDG1 ECUs can now be programmed directly in BENCH mode using FLEX — without the previous Boot Glitch unlocking process.

That means:

✅ NO Boot Glitch unlock
✅ NO opening the ECU
✅ Direct Bench programming
✅ Less intervention
✅ Reduced risk
✅ Faster, more efficient programming

🔒 KEEP IT CLOSED. WORK IN BENCH.

For our customers, this is exactly the sort of development we want to see.

The less physical intervention required when programming an ECU, the better. No opening the ECU unnecessarily, fewer steps in the process and a cleaner approach to tuning supported BMW & MINI Bosch MDG1 control units.

As a Magic Motorsport FLEX user, JSV Performance continues to invest in professional tuning equipment and the latest protocols available to us.

Whether you’re looking for:

⚡ Stage 1
⚡ Stage 2
⚡ Custom ECU calibration
⚡ TCU tuning
⚡ ECU programming
⚡ Diagnostics & coding

📩 DM JSV Performance with your registration or vehicle details for availability and pricing.
