Retune of stock ECM??

Has anyone heard of reprogramming or mapping a stock ECM? a friend of mine just had his 2014 street glide remapped for $200 and dyno'd for $300. He added Rinehart true dials and a ness big sucker intake. I didn't think a stock ECM was reprogrammable??? The guy that did this has some software and is licensed to use it? He is very happy with the results and the guy was also able to make the throttle more responsive..... Anyone have any feedback positive or negative????

As I understand it, the HD tuners reprogram the stock ECU as they don't remain attached after tuning like a power commander does.
