Something is wrong with no warning lights, please help

[papertowel]

I currently have a 2013 regal turbo and for a while now i have had a tune on it (about a year) but recently the car feels noticeably slower and I cant figure out where the power loss is coming from or what is wrong. I am suspicious it may have something to do with the transmission but I am unsure. If anyone has some insight i can provide information but I am completely at a loss currently

I assume you have not got any trans codes, or pending engine codes? The turbo may be failing but you need to look @ a capable scanner to see what the problem is. All we can do here is speculate.

Yes, zero codes at all and I have a code reader that I would assume is capable.
