Got 2 new genuine lambda sensors from work, fitted them yesterday and set up the boost to 1.2bar (previous 0.7bar) with vag com and an MBC. Problem fixed! My car runs very well now did a TB alignment on vag com and it idles better aswell. Thanks for you help guys. My car is now very fast aswell although traction is an issue and after a blast got a little bit of clutch smell guess the standard clutches were'nt design for torque like this haha, I have quite a loud 3" system which my mate reckons now sounds like a tuned evo or something on boost, well chuffed with my new turbo setup! (now saving for a clutch)
