NS - NT - NW Series Pajero

GAIN: 140+NM TORQUE. 30kw+ POWER. COST = $1695

Willall 4x4 and OFFROAD NS Pajero 3.2 DID 4M41 custom tuned on the Willall AWD Mainline dyno. Totally stock 88kw at the wheels. Custom tuned and mapped the final result was 119rwkw. Thats a gain of 36% in across the board power, and most impressively an average of near on 50% torque ACROSS the entire rev range of the engine. Drives with no lag now and better than previous economy.

From the owner - "I have been enjoying the new found power and torque in my Pajero for a while now, but just for fun I set the car back to standard to see what it used to be like...WHAT A SLUG! One trip around the block was enough, and the tune was straight back in, where it belongs!"


PB Series Challenger

GAIN: 100+NM TORQUE. 25kw+ POWER. COST = $1695

Willall 4x4 and OFFROAD PB Mitsubishi Challenger DID 4D56 2.5 liter is underrated and detuned from the factory. These engines are one of the most significant torque and power gainers when tuned. This vehicle in particular is charged with towing a heavy caravan around the country, so a good solid increase in low down torque and power combined with massive fuel savings made the application of a Willall Racing tune a logical upgrade.


ML Series Triton

GAIN: 100+NM TORQUE. 25kw+ POWER. COST = $1695

Willall 4x4 and OFFROAD ML 2.5 DID Triton custom tuned on the Willall AWD Mainline dyno. In stock form the Triton with the 2.5 is terribly detuned (particularly in 4x2 trim) with tremendous in gear lag and a small capacity for being able to lug and pull away cleanly at low rpm. Custom tuning not only unleashes over 100Nm more torque it also almost doubles the flexibility of the engine making it a truly superior drive to the standard version. Highly recommended!
