🔥 PX3 / Next‑Gen Ranger & Everest 2.0 Bi‑Turbo — Real Results From This Week
We’ve just wrapped up a few PX3 / Next‑Gen Ranger & Everest 2.0 Bi‑Turbo tunes, so here are the *actual* numbers we’re seeing on these trucks with the factory intercooler setup.
Factory Output:
157 kW (210 hp) @ 3750 RPM
500 Nm @ 1750-2000 RPM
After Our ECU Calibration:
+20 kW (≈ +27 hp)
+100 Nm
Final Output:
~177 kW (≈ 237 hp)
~600 Nm
These gains are right on the safe limit for the **stock intercooler**, which is the main bottleneck on the 2.0 Bi‑Turbo platform. Once upgraded, we can add +50HP, but even on the factory cooler, the transformation in drivability is massive.
✔ What You’ll Feel Immediately
– Stronger mid‑range torque
– Faster turbo response
– Cleaner, more linear power delivery
– Smoother gear changes (10‑speed auto)
– Better towing confidence
– Sharper throttle without the factory lag
🔧 Optional Add‑Ons
For off‑road / competition use only:
– EGR delete
– DPF delete
– AdBlue removal
– Hard‑limit torque caps lifted
– Throttle mapping refinement

BMW Z4 2.2 Performance Tuning!
Your 2004 BMW Z4 is built for pure driving enjoyment — our tune brings out even more of what makes it special.
.
The naturally aspirated 2.2L straight-six already delivers smooth, linear power and that classic BMW feel. But with our performance calibration, the engine becomes sharper, more responsive, and noticeably more alive across the rev range.
.
What this Z4 gains:
• +10 HP for stronger pull through the top end
• +14 Nm for improved mid-range torque and acceleration
• More responsive throttle for a sharper driving feel
• Smoother power delivery across the entire rev range
• Optimised AFR and ignition timing for better efficiency and consistency
• Enhanced drivability — especially in everyday and spirited driving
.
The difference behind the wheel is immediate — quicker response, stronger acceleration, and a more engaging connection between driver and car.
.
Z4 owners — if you want your BMW to feel how it should have from factory, get in touch. 🚗💨
