Welcome to HP tuners! I?ve been doing tuning for about 5 years, and I still consider myself a novice at best. However in your instance. Go to the search bar and type in some key words such as ls tuning, 5.3 tuning, etc. there are a lot of great write ups to dig through as a lot of member share a lot of great information, and you will find some great base tunes people share and some ready to go as well. However always check in the vcm suite and log log log to check for issues such as knock or limiters coming up. Also search for how people set their scanners up and download those as a good way to see how people get their information. When you download a few tunes (which also you can in the tune repository) compare it to the stock tune in your truck so you can first hand see where people are modifying and which directions they are going. Also a great tool is heading over to The Tuning School and purchasing their GM level 1 book which will include great information and a chart of where to start like a ladder diagram. Between the search on here, and The tuning School will benefit you greatly. Another great tool for basic tuning principles is HP academy. I have done all of their classes and they are reasonably priced so anyone can afford them, and they always send discount codes as well, and you can purchase tunes and break the payments up to bi weekly. I would begin with them as it will teach you the principles that give you a great inside platform to understand what is going on, things to look for, controlling timing, fuel, etc. feel free to message me if you need help, send me any logs and tunes you begin with as I can help as much as I can. My bread and butter is with the hemis but they are VE based as well, so I can navigate through them decently to at least get you a base tune going for you to tweak.
