2014 Sierra LTE 5.3l Performance Upgrades

I'm thinking about a leveling kit and larger tires. Not sure about the damage it will cause or additional upgrades that will be needed.

 

Right now I have a k&n performance intake. All stock from there. I'm considering a tuner, exhaust, headers (long tube?) I really don't know where to start, I'm open to any suggestions. It is a daily driver and I may be looking at pulling a camper behind it possibly.

American Racing makes nice headers, I'm running their 1 3/4" headers with high flow cats. As for a tune I'd go with an AutoCal and BlackBear tune.

Sweet? I'm really not sure which one I should do first. Is the tuner something I can do myself or do I need to take it to a pro?

 

I'll definitely look in to American Racing

Any idea if short tube headers would increase my towing capacity?

The autocal will plug into your obd2 to port and that's how you'll collect data for blackbear to analyze and create your tune. You can always find someone local to tune the truck but BlackBear does some pretty amazing work, updates your tunes for free if needed and guarantees their work as long as you own the truck.
