ED30 stage 2+ smoke on WOT

[Brad_ED30]

Stage 2+ edition 30 on 50k miles.
Puff of black smoke under hard acceleration - is this normal for tfsi engines? No smoke on idle or when driving normally. 
Oil usage is high but not excessive compared to VW standards.

Is this normal?

Is it like a sort of brown haze?
Fairly common I'd say. My standard GTI (stage 2+) does it when I give it full throttle for the first time after I've been driving like a nana for a while.

Someone here will probably say it's burning off carbon deposits.

Could have been tuned on the rich side also

Smoke bad enough to see in the rear view mirror isn’t good.

My stage 2+ ed30 got progressively worse for that.  It was a bad MAF. 

The problem with the MAF being so close to the turbo is PCV oil gets flicked up onto it when there is intake reversion from compressor surge.  Probably why they moved it next to the battery on the MK6.

A classic sign the maf is oil contaminated is stumbling at idle after a drive, which recovers after a few seconds and woeful mpg, plus stinky engine oil, and less than brilliant/inconsistent performance.

Who did the remap?  Ask them if they specifically set it to run rich under WOT.

Most of them do.  I was seeing 11.5 AFR hard on it with Revo 2+ (B9, T5, F8).  That is ridiculous and totally defeats the purpose of DI.  12.8 is fine and makes more power, but most tuners chuck in loads of arse covering 'safe' fuelling.

Thanks for the responses,

Can’t see any smoke in the rear view, just others have pointed out the puff of smoke on wot when driving behind.

Cars drives absolutely spot on so not concerned, just wanted to see others opinions

Have you altered you Revo settings?  IIRC, my originally supplied S1 settings were something like B6, T4, F9, and it covered my rear bumper with black soot.  I progressively tweaked the settings to B9, T6, F8 for a summer map, and B6, T5, F7 for a winter map.  No longer any black soot on the bumper, but the tailpipes are always sooty.

Systematic over-fuelling in any petrol car is a really bad idea, as it will strip oil from the bores, causing high wear, and is particularly bad in FSI motors.
