I had my 2006 Jetta Rocket chipped and I could tell the difference. But it wasn't like it made it a race car or anything. I had others ride in the car and they weren't exactly blown away or even noticed that it was chipped. That was around a 30 hp increase IIRC. Also from my reading most don't see an increase in fuel economy as they are using the extra power which takes more fuel.
