I was told that some how bmw can see there was a tune even if you have the bms cable and deleted codes. I spent extra $$$$$ on extended warranty and did not want to avoid anything.

Only way they could tell (that I can think of) is: 1) You left it on and they just happened to open up where you 'hid' it or 2) they checked the logs and saw abnormal boost levels.
With a flash tuner, if you returned it to stock, they could look for elevated boost levels (I presume they can do this) and see how many times the car has been flashed which would throw up a warning if it was higher than expected.
