How to detect a Cobb (or non-piggyback)?

So I recently bought my car used and it's apparent the previous owner tweaked some things here and there on the car. Is there a way to see if he tuned it? I've checked the ECU and there is no piggyback module. How can you tell if there is a Cobb or the like downloaded without running a dyno?
