With the Cortex tuner, you can raise the stock speed limit setting on your Dodge Durango, and you can recalibrate your factory speedometer to correct for various tire sizes. Also, this performance module lets you lift the restrictions on your rev limiter to allow for maximum rotational speed, increasing power.

If you have aftermarket performance products - such as a cold air intake, upgraded exhaust, performance air filter or throttle body spacer - you may be worried that your Dodge Durango will not be compatible with these additions. But you can use Cortex to get the most out of these parts. If you need custom tuning for these upgrades, you can download hard-part-specific tunes from the online Superchips store.

Cortex lets you adjust transmission shift points and pressure to improve your Dodge Durango's acceleration while minimizing wear and tear on your shift plates. With Cortex, you can also purchase advanced transmission performance tunes from the online Superchips store. Purchase tunes to adjust shift schedules and get advanced tuning options for each shift schedule as well as adjustable parameters within each shift point.

Monitoring Your Engine

Any time that you boost your engine's power, you should monitor the engine and transmission to avoid damage. With Cortex, you can keep tabs on vital engine data. This performance module also reads and clears diagnostic trouble codes, which ensures that you know exactly what's going on with your Dodge Durango at all times.

The data-logging feature of Cortex lets you record, display and save 1/4-mile times so that you can keep track of your Dodge Durango's performance.

  • Performance Chip Recommendation for a 2003 Dodge Durango 5.9L V8
  • I recommend unplugging the Superchips Cortex Performance Tuner, # SU3950, after the tune is made because the tuner will stay on and draw power from the vehicle battery. If you continuously leave the tuner plugged in, you could come out to a dead battery one day. Keep in mind, this is only a programmer and leaving it plugged in will not allow you to continuously monitor data. At this time we do not have any programmers that will allow you to change tunes on the go. Superchips and Edge...

  • Is a Pyro Gauge Required on a Cummins Diesel Truck with Superchips Cortex Tuner
  • It is always a good idea to monitor as many different parameters as possible when adding performance enhancing parts to a vehicle. If this were my truck, I would add an exhaust gas temperature (EGT) gauge, especially if I were using any other performance products with this tuner. The only time you really need to be concerned with a high EGT with the Superchips Cortex tuner is if you are towing a trailer with the performance tune. If you are not towing, then you should not have to worry...
