RANGER WILDTRAK • AMAROK V6 • LAND CRUISER • HILUX GR • NAVARA PRO-4X
Boat’s parked. Ramps are empty. Winter’s quiet
Perfect time to tune the ute that tows it.
► More torque.
► Better tow.
► Summer ready.
If last season exposed soft throttle response, sluggish mid‑range, or gear hunting under load, winter is the time to fix it.
A proper ECU tune transforms these trucks:
TOWING GAINS YOU’LL FEEL IMMEDIATELY
► +100–110Nm torque for confident ramp launches
► Stronger mid‑range pull for hills and long hauls
► Sharper throttle response for tight marina manoeuvres
► Smoother, cleaner gear shifts (autos)
► Optional emissions solutions for off‑road/competition use
► Reduced turbo‑lag and wider usable RPM range
► Your ute has more to give — we’ll unlock it before summer arrives.

Next up: 2016 BMW 730d, and the N57 straight‑six did not disappoint.
.
⚙️ Factory Output (Stock 730d 195 kW Version)
* 195 kW (265 HP) @ 4000 rpm
* 620 Nm @ 2000–2500 rpm
Smooth, refined, but definitely “lawyer‑limited” from factory
🚀 After Xtremetuning Calibration
We opened up the N57’s breathing, optimised torque request logic, refined boost control, and yes — EGR disabled for cleaner, cooler, more reliable operation.
.
Tuned output:
+45 HP → ~310 HP total
+100 Nm → ~720 Nm total
Stronger mid‑range surge
Sharper throttle response
More authoritative ZF8 behaviour
That signature BMW diesel wave now hits harder and holds longer
.
🧠 For the BMW geeks (you know who you are):
Driver demand, gearbox and smoke limiters rescaled
Boost request + vane control refined for safe EGTs
Injection timing + rail pressure optimised for clean burn
EGR off = no more soot recycling into the intake
Result: cooler combustion, cleaner torque, happier turbo
.
🏁 How It Feels Now
Like BMW built it this way… and then someone in a suit said “tone it down”.
Now it’s the 7‑series diesel it always wanted to be — effortless, muscular, and beautifully smooth.
.
If your BMW diesel deserves the same treatment, you know where to find us.
🏁 BEAST UNLEASHED
