dont get a chip, seriously, you have a great car there, IMO Remap the car using a reputable tuner.
If money isnt that readily available, there are plenty of options available that are good value, and proven
group buy on P torque here-they get good reviews and are excellent value http://briskoda.net/forums/topic/153737-p-torque-remap-group-buy/
alternately look into
shark performance
REVO
APR
jabbasport
bluefin
secondly-your chip wont give you 50hp anyway, thats just false marketing, realistic gains for a stage 1 are 30-40 HP. if you have the downpipe included with your exhaust system then you could realistically go to 260Hp.
