I agree returning it to stock would not resolve a mechanical issue.
I am disagreeing that the issue is mechanical and I attribute the issue directly to the tune.
Return the car to the stock map and then upload a different new map. Your problem should be resolved.

I had the left 2" inch boost hose blow off the turbo a couple weeks ago, boost went to zero but car ran fine at a very reduced power and no dash warning lights. Check the hose clamps. Bumper is going to have to come off to check vacuum lines/boost leaks further downstream.

This is basic tune from cobb. Have had SW muffler since tune - don't think it has anything to do with muffler. Honestly I don't know that SW muffler increases flow that much more than stock sport muffler. Its just a lot lighter and sounds better to me. Couple weeks ago first sign of this issue with car feeling like it was in limp mode. Seems like there must be a sensor somewhere giving wrong signal to ECU or potentially a boost leak. Feels more tune and ECU related than mechanical leak but will see.
