We get a lot of calls asking, "What do I need to do to my truck to attain a certain horsepower level?" If you've been wondering the same, below are various "recipes" of parts that are needed to reach certain power levels along with any companion parts that you'll need to ensure the overall drivability and integrity of your truck. For example, you could grab the highest setting on your programmer to make 550HP on a dyno run but for longevity sake, you would be better off with a cold air intake, exhaust, lift pump, and a lower setting on the tuner. Or we will recommend an upgraded injection pump once you've reached a power level where we have found it to be necessary. We are going to mention a lot of specific products, and these are products that we prefer through our experience. There are, of course, many other options available that can get the job done, as well.

Bear in mind that even though GM says your truck is 397HP they are quoting flywheel horsepower, not rear wheel horsepower. On a dyno, the actual rear wheel horsepower for these trucks is about 350HP. Please don't get sucked into the trap of adding all of the manufacturer stated horsepower gains for the individual products together to estimate your horsepower. This will only lead to disappointment! There is typically a substantial amount of overlap when combining products, but this is a necessary evil.
