Interesting, got more info such as a website page?
Just looked, that's the same chip my daughters 97 Golf had when she purchased the car. Yes it make it's run better but I don't think anything close to 11hp. The fine print states "up to 11hp" I can tell you the chip does advance the timing because her car would ping with 87octane fuel and sometimes also with 89. So I think all they do is "play" with timing. Raising the RPM limit does nothing if you don't have another camshaft "tuned" for the extra RPM range. I think to see a real world power increase you will need to go the complete upgrade, chip, cam, exhaust, intake mods.
