Advanced Options

With the Cortex tuner, you can raise the stock speed limit setting on your Chevrolet Silverado, 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 Chevrolet Silverado 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 Chevrolet Silverado'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 Chevrolet Silverado 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 Chevrolet Silverado's performance.

  • Performance Programmer Recommendation for a 2011 Chevy Silverado with 5.3 Liter Engine
  • To me, the best bang for the buck is going to be the Bully Dog Triple Dog, # BY40410GMC. It can add as much as 35 horsepower and 40 foot pounds of torque. It is also a comprehensive gauge display, and the driving coach program will help maximize full economy. It is only a little more money than the Cortex but has more features. I have included a link to the installation details for the Bully Dog for you. You can read up and compare the different programmers available on our site. I have...

  • What Should the Shift Pressure be Set At Using a Superchips Cortex on a 2008 Chevy Avalanche
  • I spoke to my contact at Superchips about the Cortex tuner # SU2950 and the shift pressure on your 2008 Chevy Avalanche. He stated that it all depends on your personal preference. He recommended maxing it out, try it, and if it shifts too hard for your liking back it down. The harder it is set the more efficient it will be. The Superchips Value setting is an option and is just where they think it should be for a given vehicle. But ultimately it comes down to what you want.

  • Can the Tow Mode on a 2011 Chevy Suburban be Used at the Same Time as a Programmer
  • The tow button and mode on your 2011 Chevy Suburban does a similar function as the tow setting tune on a programmer. It will change the way the transmission behaves to the optimum settings for towing. But a programmer will provide more power and torque as well. If using the programmer on a tow setting you would not have to use the tow button on the vehicle at the same time but you can. I have included a link to our help article on programmers for you to view.

  • Programmer and Cold-Air Intake Recommendation for a 2009 Chevy Silverado with a 4.8 Liter
  • You will gain about 11 horsepower and 11 ft. lbs. of torque with the Superchips Cortex Performance Tuner # SU2950. You should feel this power increase but it will not be a night and day difference. To maximize the power gains a cold-air intake system would make a nice power increase as well. Check out the Bully Dog Rapid Flow Cold Air Intake System # BY53253.

  • Performance Programmer Recommendation for a 2008 Hummer H3
  • There are programmers available for your 2008 Hummer H3, but the Bully Dog Triple GT is not one of them. The Superchips Cortex Performance Tuner # SU2950 that you referenced is confirmed to fit your vehicle and would work well for you to give you increased power.

  • 2003 Hummer H2 6.0L Programmer Recommendation
  • The programmers we offer are generally designed for vehicles with very light modifications or being totally stock. The Superchips programmer part # SU2950 has been confirmed as a fit for your 2003 Hummer H2 with a 6.0 liter, but if you have long tube headers I wouldn't recommend one of our programmers. If the headers you have are shorties and you just have a throttle body spacer and an intake this programmer would work well. If you do have long tubes you will want to look into...

  • Can Advanced Transmission Options be Used with the Cortex on a 2009 GMC Sierra 1500 5.3 Liter
  • The Superchips Cortex, # SU2950, and really any of the programmers or programmers that come with monitors for your 2009 GMC Sierra 1500 with the 5.3 liter do have transmission only tunes preprogrammed so you can just maximize shift points for the transmission. Others allow you more control. The Cortex for example will allow you to change the shift torque and shift points on your 2009 Sierra 5.3 liter. I have included a link to the installation instructions for you. I have also included...

  • Programmer, Cold-Air, and Cat-Back Recommendation for a 2011 Chevy Silverado 5.3 Extended Cab
  • The Superchips programmer part # SU2950 that you referenced has been confirmed as a fit for your 2011 Chevy Silverado with a 5.3 liter engine. For a cold air intake the Bully Dog Rapid Flow system part # BY53253 would be a great choice as it advertises gains of up to 10 horse power. For your extended cab truck you would want the Magnaflow system part # MF17102. Your truck will be noticeably faster, louder, and more efficient with all of these products.
