I know what you are saying 427, with more air, the ECU will add more fuel and thus more power.
Where you are wrong is the ECU controls the boost, so if you make air denser, then the computer will cut boost so the MAF will see the same volume of O2. You can't control air at the MAF by changing plumbing.
Since decreasing air temps only increases max hp at WOT (below that the throttle body is the biggest restriction), the turbo will always be spooling and its output will be limited by the ECU.
The denser you make the air, the less boost you will get, and you can't make 14.7 psi air cold enough to make up for 20 lbs of boost. It certainly won't happen at 150 mph. If you can though, you will be a billionaire.
GM had previously planned to release a cold air intake for the 2.0, but even that was accompanied by a tune. They never released it, but maybe if you google you can see old articles on it archived somewhere. The original info on it had hp/torque increases listed but it had a note that said dealer installation with tune was required.
If GM can't figure out how to get their own engine/parts to improve performance without a tune, I'm sure they (and a thousand other companies) would hire you in a second.
When you install higher flow components, you will get a temporary hp/throttle response increase, but it will fade quickly as the ECU adapts.
