Most newer vehicles (Nox and Terrain included) can't be "chipped" because cars no longer use chips. You could reprogram the ECU with an aftermarket device, but you have to be careful with such things....aftermarket companies don't do extensive testing for their new settings. You could put one of those straight intakes on the engine to get you a little more power...but those things are risky because they can take in water as well. Your best bet is a low restriction exhaust system...I plan to do that when then factory setup gets up there in age.
The new Camaro, Regal, Equinox and Terrain cant be tuned without having a serious chance of having your warranty voided. Previously, you could do it without the dealer knowing but with the new ECUs it actually tracks the amount of flashes done to the software. If your dealer suspects that your changes caused the fault, you are toast.
Now, I dont doubt that an intake would seriously help at least with some extra power. The stock stuff is pretty restrictive.
There is nothing wrong with doing a CAI/exhaust on a vehicle. A tad more power is never bad.
Heck, with $200 I just knocked off .6 seconds and gained 4 MPH in the 1/4 mile with my G8. Now Im running what a Camaro SS runs yet I got my car for $10k less than a Camaro and have a much more useful daily driver vehicle.
