Can you put a chip and programmer in ford 7.3 diesel?

You can't simply "put a chip and programmer" into a Ford 7.3L Power Stroke diesel in the same way you might with some newer vehicles. The 7.3L Power Stroke (pre-2003) uses a mechanical injection system, meaning fuel delivery is controlled by mechanical parts, not an electronic control unit (ECU) that can be easily reprogrammed with a chip or handheld programmer.

While there are performance modifications available for the 7.3L Power Stroke, they are generally focused on:

* Injectors: Upgrading to higher-flow injectors to increase fuel delivery.

* Turbos: Installing a larger turbocharger to improve airflow.

* Tuning: While not a "chip" in the traditional sense, some specialized shops can adjust the fuel delivery via modifications to the fuel pump and other mechanical components, effectively "tuning" the engine. This isn't a plug-and-play solution like a programmer for an OBD-II vehicle.

* Exhaust: Upgrading to a less restrictive exhaust system improves airflow and can increase power.

In short, the concept of a "chip and programmer" doesn't apply to the mechanical injection system of the pre-2003 7.3L Power Stroke. Modifications require mechanical expertise and are often more involved than simply plugging in a device.
