This Stage 1 tuning file is professionally engineered for the Isuzu NPR 5.2L commercial truck, equipped with a Transtron ECU. This calibration is specifically designed for a working vehicle, focusing on delivering a significant increase in torque to improve its heavy-duty capabilities and overall efficiency.

Our remap transforms the truck's performance under load, providing much stronger pulling power for handling heavy cargo and climbing steep gradients. The optimized engine parameters can also lead to noticeable fuel savings on long routes, reducing operational costs. This tune also includes the removal of the top speed limiter (Vmax). It's a safe and reliable software upgrade to make your Isuzu NPR a more powerful and economical asset.
