"Overboost" is simply when the car sees more boost pressure than it has commanded. It is a tuning term, not a mechanical one. It is not very common that it happens, but there are many safeguards in place to ensure that if it does happen, the ECU takes precautionary steps to prevent any engine damage. The tune is very safe.

While the Stage 1 kit is a good value, bear in mind that the intake does not really add any performance. You'll be gaining low single digit horsepower gains at peak power. You'll be much better off waiting for the BNR V2 downpipe to come out, which should be in the next few weeks, and getting just the tune to start out: BNR Tune 2011-2016 Limited chevrolet Cruze 1.4L Turbo

I've been tuned for a couple of years and have put some very heavy driving through this engine. Make sure you're using a good oil (specifically, I mean AMSOIL, as most group 3 oils can't handle the stress the turbo produces when tuned long-term).

The boost threshold is set in the tune; I'm not entirely sure what it is though. The issue sometimes comes from inconsistencies in wastegate adjustments from the factory. Once those inconsistencies are accounted for in the tune with a datalog, you won't have anything to be concerned with.

Thanks for clearing that up! Im a mechanical engineering student so mechanically things all make scene but tuning the ecu is very new to me.

I want the intake more for improved response and sound, I am aware that I wont see much power gain from it. I didn't want the down pipe as dosent it void power train warranty? Im sure if it dose so does the intake but my logic with that is that i can put the stock one back in in 20-30min or less and take the car in, the down pipe would need more work.

If you're getting the car tuned; that warranty ship has sailed. Fortunately, we don't ever see any issues caused by a BNR tune, so it isn't likely that your dealer would have reason to blame it.

Downpipe would need more work, but would also provide better results. Up to you really. I have an intake, but bought it used.

Depends on the dealer. My dealer doesn't care. Took it in for a bad flywheel and they said nothing about the mods and the tow hitch. Other dealers might try to weasel their way out of warranty work by blaming mods. I've seen them blame an intake on completely unrelated issues.
