Edition 30 smoking on boost

<< < (5/5)

Dan_FR:
Are you noticing this smoke in the headlights of cars behind at night, or during the daytime?

Cosmos:
The cars engine side has revo induction,uprated fuel pump internals,bcs turbo back powervalve exhaust with sports cat,airtec intercooler and a r-tech stage 2+ map.
Have had the injectors cleaned and the valves walnut blasted too.
Car has 376bhp and 423 lbs torque

Its 3rd and 4th gear under heavy load during the day you can notice a smokey mist in the rear view mirror but am sure it doesnt do it every time.
Thought if all the stage 2+ Tfsi engines did it there would be more posts online regarding it.
Needing the timing belt done next spring so might see about going back to rtech for that and asking for the map to be changed even if its lower power to eliminate it.

I would say that it is running rich.  I get the occasional puff of smoke from mine when under load, usually after it has spent a while running around in town. The smoke went from black to grey after leaning off the revo sps fuel setting and fwiw the car ran crisper for it.
