As to the horsepower issue... Yeah, with 180 ponies and 1100kg it moves pretty darn good
But there's a rumour in the Pug forum on the MotorTalk.de BBS that some tuning company is bringing out a kit this spring that'll raise it to ~220-225... not sure if I'll go for it though.
I'm currently considering adjustable shocks&springs, because it stands pretty high as it is. But it'll have to wait until spring when I get the summer wheels on.

You being swedish, you should be able to read the Danish Peugeot forums, where there is a lot of information about tuning the engine of the 206. Check www.hi-speed.dk and www.pugs.dk - I know that the 206 GTI has proven to be VERY hard to gain extra power in. Various things has been tried, but without any particular luck.

Cheers
