The ECM compensates for most mods.
These tiny engines are putting out more than what a six would have years ago. I once had a Ford with a 2.4 (144CID) engine and, while loveable, it was a turtle. Our 2.4 Tigershark (Kittenfish) engines are putting out more than double what that Ford did.
The Tigershark is already over 1HP/CID. Even NASCAR is only running 2hp/CID.
What usually happens is after installing the gizmo the owner drives it harder than before "to see what it will do" and sure enough, its putting out more because more was demanded of it.
As above, FCA has a room full of engineers working on extracting every bit of power out of these tiny engines. The aftermarket industry thrives on the same sort of people P.T.Barnum thrived on.
Best thing you can do is reset the ECM, then drive it hard for the next hundred miles. It will learn your style and give you higher shift points. Higher RPMs will give you more than a pile of gizmos.
But cars are fun to play with. Old cars were more fun because there was more we could do with them. Newer cars are already maxed out. We can still get a better sounding growl by playing with the exhaust but too much of that can affect valves. Actually, from inside under moderate acceleration I think the Compass has about as good a sound as I've heard from anything other than a V8, though my old Grand Prix with the V6 sounded a little throaty.
