Smoke?

[JRG]

I have been experencing lots of smoke lately @ take off. No box currently, only injectors, cleaned air filter & fuel filter. Power seems to be normal, although after long slow-speed run times there is burping/bogging @ take-off. It has been to the dealer for misc. crap, at which time they said they "updated the computer program". Has only done this for about the last 5k miles (that I have noticed) Definatly not from day one.



Any ideas befor I call the dealer? Thanks.
