2021 Isuzu DMAX and Mazda BT50 Tuned 4JJ3

Before Tuning

140KW / 450NM

After Tuning

183KW / 590NM
Isuzu’s long-serving 4JJ1 engine has served its purpose, but the 2021 D-Max and BT50 are equipped with a new 3.0 litre turbo diesel that is all-new from top to bottom: cylinder block, pistons, head and fuel injection system are only carryovers of the previous model’s components in the engine.

Thanks to our development we can tune the new 4JJ3 from 140 KW at the crank to 183 KW and from 450 NM to 590NM with a minimal boost increase and safe air fuel ratios for heavy towing use. Development was done here in house on our 4WD rolling road dyno. 8977996891 and 8977996890 versions have been developed. As you can easily see, the gains in both HP and torque are undeniable. These are genuine results, from actual 2021 Isuzu DMAX and Mazda BT50 engines we tuned for our customers. We take pride in being the best at what we do for petrol heads like us.
