You will need a MAP sensor pipe for A3 FMIC install as it's normally mounted in SMIC (unless it's AGU, in which case it has no MAP sensor!)

You will learn a lot more from this post than the FMIC sticky...
How you go off the turbo/over the rocker and incorporate the DV is open to interpretation and you might have to use your imagination a bit... I think I probably went about it a bit of a weird way, but hey, it works!
Also, I think how "higgysmalls" came off the IC and back to the TB may be a slightly better way of going about it... Again though, it's subjective and you have to use your imagination a bit.
Remember you can always order more than you need from autosiliconehoses.com, have a play about and return what you don't need... They're pretty good like that.
Good luck!"
As mentioned, I will get round to writing up more information for A3/k03 FMIC soon!!!
