I've not posted much on here but have certainly got a great deal of information which has been invaluable.
I've sold my 306 HDI Dturbo (chipped) and now have (flame suit on) an Alfa 156 2.5 V6. Bit of a change I know, but hey, you only live once.
Thanks for all the help - if you want any info on chipping, post as I'll be reading for posterity.
