The smoke could also be because the vRS uses a DOC (Diesel Oxidation Catalyst)which are prone to sooting up if you are cruising for a long period. If you then put your foot down the extra heat and air flow will clear the soot. I work for a company that makes and develops them.

Mine tends to be a tad smokey on a boot full, all standard.

Most of us dont run cats so that's irrelevant really.

It's just due to over fueling on my map to get the power and cool the turbo

Most generic maps will wind the fueling up hence the smoke

Yes I understand over fueling will cause black smoke. I just wanted to add that it isn't the only cause.

.....Was behind a Peugeot van this morning and it sped away under a cloud of smoke

I bet you "had him in the twisties" though

Excuse me BEHIND!! a Peugeot VAN and IT SPED away are you in a Honda Civic by any chance :-)

:yes: Should've had a mustang slaying 2.0l Fabia. You'd have taken him like a King
