After de-cat of Prado 4,0L V6

I've noticed that after I de-catted my V6 that she tenders to smoke on start-up in the mornings, has anyone else noticed this after de-catting their V6's

At first I thought it was oil smoke/valve stem seals, but you can smell fuel rather than oil. At the last service I ask Toyota to check that all the sensors were working and all was good.

Any ideas????

Myne het die petrol reuk gehad voor ek die cats uitgehaal het en was dieselfde na die cats uit is.
Het nie regtig opgelet oor die rook in die oggend of na dit aangeskakel is nie.

Brandtof verbruik op die oop pad het 'n klein bietjie verbeter, maar dis klein.
In die verkeer is daar geen verskil.

No problem like that on my de-cat'd 4L V6... I believe the O2 sensors need to warm up a bit before they give accurate air/fuel readings.

Is it not related to the lower ambient morning temperatures in winter?

I have 208 000 km's on the clock, the consumption improved by around 1L/100km's. I also had a roof rack on that I now take off when not in use and the further improved the consumption by almost another 1L/100km's. I'm now about 1,5-2L/100km's better off.
