For what it's worth, my '94 CS Turbo 5-speed with an Aero ECU runs quite differently on 87 vs. 93 octane gas; premium gas allows significantly more boost at all speeds, starting from zero. I did not find this difference in performance between 87 and 93 with the original "full boost" CS/CSE (same in '94) ECU, in fact I could hardly notice it.
You can try running 87 octane gas in your Aero and it will still run, but with less performance. You might also find that the mileage changes a bit as the ECU will dial back the spark advance to accommodate the lower octane gasoline. I have never quantified it to my satisfaction, but it's possible that 93 octane gas makes the car run more efficiently and will pay back the premium price with increased mileage (but this may be wishful thinking). Oh, not to mention the grin factor when you step on the gas.
