The Isuzu NPR is a hell of a truck at an affordable price — but it's got one thing going against it: the exhaust gas recirculation system (EGR). Often used for short hauls, the EGR system in the Isuzu NPR often doesn't have the necessary time to warm up and do its job properly. With 3K Calibrations custom tuning and EGR delete kit, you'll be able to get more HP and more life out of your Isuzu engine.

The Isuzu NPR is equipped with an:

Isuzu 4HK1-TC turbocharged intercooled diesel

After Tune – 542 lb.-ft. @ 1,850 rpm
