    So to be honest, I thought I was going to be getting a Dodge with a 5.9L Cummins. Well the chips landed were they did and I'm now the proud owner of the truck in my sig. I really love the truck, but to be honest I just don't know as much about a Chevy gaser as I do a Dodge Cummis. So with Cummins there were certain upgrades or changes that were suggested to be done to the truck. Almost must do's. Are there any most do's with the new body style Chevy's with the 5.3?

    :sign0016: To the G.M Family.......The 5.3 Liter you have is a Great Engine, with that being said and Depending on your budget.......There are the 3 Bolt-On's that just about everyone does....CAI,Headers and Cat Back Exhaust......After that a Tune either Hand-Held or Custom.

    OK I did a search, but what does CAI stand for?

    Also, I know I want to do a leveling kit, but I figure it won't look good unless I do tires and maybe new wheels. Of course my truck cam with new tires, so I realy don't want to throw money and new tires since I don't need them.

    I'll have to check the tires for the size, but I know the wheels are 18"

    Which is usually inaccurate. Most CAI don't pull all that much cold air, most are open chambers right into the engine compartment. I know they usually have a heat shield, but that doesn't stop any air from going right around it. Some truly pull "cold" air from outside. We really should start categorizing them as CAI and STR (Silencer Tube Removal) or ISR (Intake Silencer Removal).

    Anyhow most get their increase simply by higher airflow.
