When are you getting smoke? A little on hard acceleration, at startup, or all the time?

Some smoke can be normal, I hear. I get none however. Lots of black smoke means unburned fuel, so it could be running rich. Look on the POCUK site for info on turning down the fuel pump. Who did your pump seals? From what I've read, you generally need to get a pump calibrated after it's been worked on.
