I just purchased a 2013 Silverado with 75k miles on it, bone stock. I would like to level it at least, maybe an inch in the rear to accommodate larger tires down the road.
Does the 1.5 inch level it or is the 2 inch needed? I measured to the top of the fender wells in the rock of my drive way and it showed only 1.5 inch would be sufficient. I do not want a saggy rearend truck. Level, level, and level is what I'm looking for. Is a half inch a big deal?
Or do I get a 2.5 overall lift that compensates for the leveling and has blocks for the rear? Says it will accommodate a 285 tire.
Anyone raise or level theirs and have suggestions or testimonials on kits?
I would also like cold air intake suggestions, exhaust suggestions, and custom tune ideas. Are they worth the gain in mileage for the cost. It's a daily driving, kid toting, grocery getter. I would like it to sound good, ride good, look good, and perform well.
I'm assuming it has the Active Fuel Management on it and would like to delete/turn off that. I don't want to pay twice so that will probably wait till the tune comes along, unless there's a cheap and easy way to do it separately.
And the side body moldings, are they just stuck on? How does one go about removing them? Little heat and some WD40 to get the glue residue off?
Any advice and suggestions are greatly appreciated. This is a step up from my 95 Tahoe and I'm looking forward to a new "toy".

Keep throwing money at it, it'll get better...

I have a 2014 GMC Yukon 5.3 L. After reading about the lifter issues that are bound to occur because of the AFM, at about 100,000 miles I had a local speed shop reprogram my PCM to delete the AFM before any lifter issues started.

Their reprogram made many other changes to my PCM that effect / improve engine response and economy. Before any changes the I typically got 17.3 mpg on extended trips. After deleting the AFM I’m getting 19.1 mpg. Go figure.

I would love the completely remove the stupid lifters, cam and related parts but that is a lot of work and expense. For now, I’m happy to just have the AFM deleted in the PCM. But if any failure in the engine occurs, I’ll bite the bullet and do the cam and lifters swap.

Wow... That is a very informative website and that gentleman knows his stuff. He states that some handheld tuners will not do what he can do. I've purchased a Diablosport inTune 3 Platinum that does tuning, not just the AFM delete. I hope this covers my bases. I hate the thought of being out of my truck for a week for shipping the computer off.

Some tuners will do a core charge to send you a PCM in advance so there's no downtime.

Pretty sure just like many other MPG-related scams, AFM might work in theory so they could meet CAFE requirements but in real-world driving does not deliver. And in the end, the owner suffers as failures start racking up..
