Is my ecu still tuned?

Ok guys first of all forgive me if this is a dumb question as I am sure some will. Anyway a month ago I purchased a 9th gen 2014 si fb6 black beautiful car, the original owner had bought the car brand new off the lot while he had it he of course done about every bolt on mod possible I do have the list if anyone needs to see what has been done. My question is this I wad told he also had it dyno tuned with hondata flash pro but once I started going through the car there was no flash pro module so could it be he traded the car in with the ecu still tuned or when he took it physically out of the car the ecu went back to stock form? In my opinion the car is still tuned unless the bolt on mods with no tune made that much of a difference. So can someone please help with this question or tell me how or if there is a way I can findout. I'm still planning to buy a flashpro but I haven't had funds just yet
