I can definitely give you a package that includes a performance tuner, exhaust, cold air intake, and transmission cooler for your 2018 GMC Sierra 1500. These upgrades will be sure to increase your truck's performance and fuel economy.

For the tuner I highly recommend looking into the Superchips Dashpaq+ Performance Tuner # SU20617 which is made for the GM 5.3 motor. This has pre-loaded tunes for your vehicle that are setup for towing, economy, performance and more. It features a nice looking 5 inch touch-screen monitor. A really cool feature is the Virtual Drag Trip which allows you to conduct 0-60mph pulls along with 1/4 mile and 1/8 mile tests.

In regard to the exhaust system, you could go with MagnaFlow Cat-Back Exhaust System # MF15267 which will retain the factory exit location and factory look, aside from having a nice stainless steel tip. For a slight increase in price I would just go with the MagnaFlow Black Cat-Back Exhaust System # MF15361. This has a strong ceramic black coating to protect the exhaust and give it a really nice and aggressive look. It is a dual tip design which exits on both sides of the truck in a straight-back fashion. Both of these systems are high-flow performance exhausts that will sound great on your Sierra and boost engine performance.

Finally, for a transmission cooler I highly recommend going with the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class IV - Efficient # D13504. This is larger than most coolers and will work well for your Sierra. You will need to add Adapter Fitting for GM # D13035 which connects the radiator to the transmission cooler quickly and easily and requires no cutting lines. It is also recommended to get Mounting Kit # D13002 to make installation easier. You also may need to add Derale Transmission Replacement Hose, 11/32" ID x 4' Long # D13003 since some vehicles require a longer hose.

I have attached detailed demonstration videos for you to check out.
