May need to put my mods on hold just now as the car started being a fud again.
Recently installed my catch can and the car stopped doing its dodgy idle for about 2 days, started it up this morning and first thing i noticed was theres a hell of alot of smoke at startup, from first looks its grey so i dont think its anything too sinister just moisture built up in the exhaust but it takes a fair old tme to clear. second is the car is making a wooshing sound as i accelerate which i assume is the turbo but it sounds really loud. ive got a full stainless and a decat but it really does sound alot louder than im used to. All the boost hoses are on and secure and my turbo to pancake pipe is an agu done up with mikalors so its air tight that was the first place i checked. 3rd thing was when i put it back on vag com and block 32 is showing (-8.6%) Idle & (+6.8%) Partial which isnt good so did a quick fault scan and got the following:

can anyone help me with what i need to do to sort this?, like i said ive got a catch can in place and all the joins are air tight as is the capped off vaccumm port on the manifold. My next port of call was the sai delete and n249 bypass to eliminate them as the culprits but with the small piping for the n249 i dont see even a big split could cause that much fueling correction.
Any help appreciated
