Didn't know Andy mapped the Leon's. From experience when we used to map the vw group the lcr can and will do 280bhp with simular torque with supporting mods.
Apr stuffs too mild, where the revo spikes the turbo, For actually mapping them Myself the custom code software is great and about £300. We used to be agents for custom code, and I can vouch for it being great software, one of mine pulled around 280bhp on phase two software. Don't go for the revo trial. It locks the ecu and also puts a crap base map back on,
i've just left the VAG fold after many years pouring money into them, if you ever need it scanning for fault codes i'm happy to do it for you, i can scan and clear codes and in some cars activate hidden features if you need forums for advice i would suggest http://www.clubgti.com/content.php for info and help with anything VAG related and for meets and general chat and banter http://un-phased.co.uk/
Take it you haven't used any of the new code from APR or Revo? They are both a different breed now, the 1.8T stuff is great and the 2.0 TFSI stuff is surreal.
