The Isuzu FRR 600 belongs to Isuzu’s F Series, categorized as a mid-sized truck.

This post focuses on the 2013 Isuzu FRR 600, equipped with a 7.8L 6hk1 diesel engine. At Alt Tune, we possess the technology and expertise to transform this popular truck into a robust workhorse, enhancing productivity and the overall driving experience.

Alt Tune’s custom tunes stand out as they are tailored to meet our customer’s specific needs, vehicle, and driving environment. We employ Alientech KESS3 to flash the tune into the ECU.

Investing in a custom tune from Alt Tune makes your Isuzu FRR 600 more efficient, saving both money and time for your business. An ECU tune proves to be a worthwhile investment that lives up to expectations.

To further enhance your Isuzu FRR 600, we have developed an emission solution to address issues arising from the factory emission settings. This upgrade eliminates problems caused by default emission settings, resulting in a more reliable truck. Not only does this investment save money in the long run by reducing costs and downtime associated with these issues, but it also contributes to a more efficient and reliable operation.
