Most of the chip guys say 50 to 65 hp increase.  This is in the order of 210
to 225 hp, which is a bunch more than the stock 162.  My seat o'd pants says
it goes real good.  I discussed 2.2 bar w/ a list expert, who can feel free
to chime in here, and his concern with 2.2 bar is turbo and IC problems.
The stock turbo will overspin (esp. at +3,000 ft altitude), and the stock IC
is not up to efficiently passing 2.2 bar.  However, with an upgraded IC and
turbo (like an RS2), 2.2 is not a problem.  There are those who run 2.2 bar
w/ stock components.  I don't know their experience.
