The easiest, cheapest and simplest thing you can do to improve the running of your engine is to always use a Top Tier Gasoline.

Home | Top Tier Gas

After that, the second best thing to do is replace and regap your spark plugs. Someone else will know the ones and gap to use.

Proper cold air pressure in your tires, as specified in the tire placard aheared to your driver's door jamb, is the third best thing to do.

I use regular gas, I PERSONALLY don't see benefits outweighing the cost dofference, but I will say performance difference is very noticeable, I dont get much better gas mileage and the performance on regular doesn't bother me, but a lot of guys recommend using premium so I'm of the very few!

I am currently untuned, I have replaced my spark plugs to ngk bkr7e-4644, like tomko suggested

As far as tune, if you want, go through my accounts recently posted, the two most popular tunes are the BNR (bad news racing) or the trifecta, I posted a thread recently trying to get a direct comparison from consumers of the two, I personally found it helpful and lead me to deciding to go with the BNR

I also drive a 2011 cruze ltz

Welcome to the forums. As stated above read up on post about tunes in Gen 1 section for about a year or 2.

When I got my car new it hated 87 so 93 was all I had to go off of. ECU updates for the auto only still left me out there in the cold. When I was tuned the car drove like it should have from the factory. You won't be Ford Focus ST fast but you will sure feel like it. After tune you can still run 87 but the car won't perform at it's best on it. If you happen to decide BNR is for you and you choose to go to a local vendor instead of getting a handheld you can add your location to your profile and talk to Jerry. he should have a list of who is near you. The plugs in your car should have been changed out by now. If not there is a few threads on those as well. Of all the plugs I used, I liked the BKR7E mentioned above but they lose their gaps quickly when tuned. 0.028 would be 0.034 in 4000 miles the way I drove. I ended up settling with the BKR8EIX 2668(the 4 numbers you need to search auto zone or advanced auto since the plugs that will come up under vehicle search are not that great)

Before we get too far ahead into mods, verify recalls have been completed for your car at the Chevy dealership.

Welcome to the forum and as stated above, try running a tank or 2 or top tier/higher octane gas. You will notice better pick up and more response from the engine. Yes it costs a little more but I found the trade off/price vs. power differential worth it and you may see an improvement in MPG as another side effect. Also with 100000 on the clock check the plugs and see how they look. The plug # is 41-121 for AC Delco if you want stock plugs. That is what I ran and had no problems. FYI if there are any questions you have about your car, search the forum and chances are we talked about it or just shoot out a question.

Tuning does make a huge improvement in performance......however some 2011's did have issues with piston failures. I had a 2011 ECO and the pistons failed at 24000 miles, not sure if the tune made that happen. Just a heads up. Like merc6 said, your not going to be Focus ST fast but way better than stock.
