how to calculate pork ribs calories??

Hi, I just had homemade bbq pork ribs (I did not make them) and weighed out when cooked it was 261g. I do know 2 tbsp of the barbecue sauce used is 36g for 60 calories, which I think it’ll be safe to say 2 tbsp was used, and after I ate it I weighed the bones and subtracted, giving me 200g of meat eaten total. But when I google im getting wildly different ranges for pork ribs calories. Could someone give me a good estimate per 100g? I think the ribs were cooked in oil so whatever estimate I’ll just add 50 calories on top
