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.
