Piggybacks work. They have especially good results on forced induction motors. Just to add and summarize what others have said the chip alters feedback to the car's management system to increase fueling and possibly alter turbo boost and spin up rpm.
Fitting a piggyback will void your warranty and maintenance plan. Though manufacturers will tell you that it's quick and easy to fit/remove the chip prior to maintenance, most modern day car's diagnostic logs will record sufficient data to indicate that the engine was running outside of it's default parameters. In terms of warranty/maintenance the gains don't justify the risk IMHO.
Do some research on the equipment you chose to fit to your car. Turbo chargers can drastically increase engine output, though couldn't imagine 3x OEM output. There is a price for most gains though. Increasing boost leads to increased engine temperature, potential increased exhaust pressure and as results increased fuel consumption (like anyone cares about consumption when they want to go faster). Engine gaskets, pistons, heads etc. have operating limits that are easy to surpass with a little tinkering. There are moderate piggybacks with track record to show increased performance at no significant reduction in reliability. My 320i for example could easily produce 40kw and 70nm more purely on the back of software. It can't however match the performance of the 328i with it's forged pistons.
Once my motorplan and warranty expire it's piggyback and downpipe time!
