Ideas to wake up a 5.3 Suburban
Ok, I am still basically a noob when it comes to performance modifications. Thats basically why I joined up here, to learn more. I have a 2001 Chevy 2wd Suburban with a 5.3 liter engine and a 4l60e transmission. So far, I have a Blackbear 87 octane tune, a vette servo in my transmission, and I installed 2006 electric fans. Nothing else has been done, all stock intake, exhaust, and everything else. This is also a family hauler, so I can't exactly get too wild with it, and I am also on a pretty tight budget. I just want some ideas on other stuff I can do to get more get up and go out of this big lead sled. The Blackbear tune was a HUGE improvement in itself. But now it has me wanting more. So I was thinking maybe an Airraid intake tube, any other ideas for stuff I can do besides a Supercharger or swapping in a 6.0?
This engine just broke 100k miles, so I would like to avoid doing an engine swap because I know that this engine has a lot of life left in it.

The more you tear into the engine the less reliable it becomes. Keep in mind that if you have to add or change parts expect to be down for the day.
You could do things like a cam swap, and or better heads.
You will eventually start breaking parts on your quest for more power.
The best bang for the buck would be a 6.0L and a retune.
If your content with the 5.3 then do a cam swap. With new parts, you will be in it about $500-$600
Depending on what gears you have, you could do a gear swap. Depending on Labor rates and parts it could run $500-$700 range for gears and swap. You won't gain power put it will make you quicker.
What ever you decide to do make sure you get the tune adjusted accordingly to get the most gain out of your modification.

The most your gonna get is like another 15-20 with bolt ons.
You could do CAI, Exhaust, but at best you may get another 30 overall.
A cam alone can net you another 50 and make a world of difference.
as mentioned to get the most out of any mod get it re tuned.

Airaid air tube and long tube headers are the best next bolt-ons. You'll have to get retuned then. Beyond that you are looking at a cam swap or a power adder like have been mentioned.

Thanks for all the suggestions guys. I am already aware that I'll need a retune. I actually already got it retuned about a month ago, just needed him to update my new tire size and I had him adjust the fan turn on temperature. I had him lower it to 203° because it gets awfully hot here in Louisiana in the summer.
Justin told me that I shouldn't need a retune if I just get an intake unless I hear some pinging in the engine at high RPMs. Same for exhaust unless I to headers and true duals. But he did say that if I added both an intake and exhaust that I will need a retune. Regardless, I will email him and ask his advice on retuning no matter what I end up adding.
