Silver 64,
That is a sweet intake and mine will be here later this week. I have installed many CAIs on multiple vehicles, all with great results especially if you join them with additional bolts-ons and good tuning software. The key here is if you are going to let more air in the motor, you have to let it out. The first restriction begins with the inlet, which is the factory airbox, which contains your typical paper filter and an additional carbon cotton filter. Then if you move to the exhaust, the outlet restriction is the factory resonator and its design. Then, if available, which is limited for the 19s, is adding a good tuner in the mix. Think of these three things as a badass three course meal--a delight for every patron if prepared right.
So here is my plan to put what I have and what I believe will be a great combination. I recently replaced my exhaust resonator with B2Fabrication 14" replacement muffler and have, sitting in front of me is the Edge Pulsar piggy back tuner. From the research and those who I have talked to, and the excellent credibility Edge has in the tuner world, has convinced me that Edge Products have in fact modified spark, fuel table, shift logic, and throttle response for their various 8-levels of performance. While minute in there effect, remember, these are big heavy trucks, the gain is noticeable which in my experience will only be enhanced with complimentary inlet and outlet improvement. That is a deal winner for me. I will add both the S&B CAI and Pulsar Tuner together.
Finally, any time you disconnect the negative side of the battery when doing any mods (please adhere to this) is to give the ECU time to relearn everything that you modified; this is critical and for the most part should be achieved within 500-750 miles based on your driving style, fuel you use, temps, and other conditions. Hope that clears up the benefits of bolt-on/add-on devices. Just follow and learn from those on this and other forums. Do some research and you will know the who and where to go to modify your truck with the best products with the best results.
