I'm thinking about putting the Bosio's in my 350SD - the idle was REALLY rough when I got the car several months ago. It has improved significantly since I started running B20 and WVO (GreaseCar) but the idle is still not as smooth as I would like to see it. It is typically very smooth on WVO, but I can feel the difference as soon as I switch to B20 to purge the system, and I still have some smoke under medium/heavy throttle. It's not black smoke since I'm burning WVO. I'm not worried about the smoke for any particular reason other than perhaps it is a sign of incomplete combustion - and I would like to get as complete a burn as possible so I can avoid carbon deposits/polymerization from WVO. It's not something I can't live without at this moment, but ultimately I'd like to get the best performance I can from this motor (as well as do whatever I can to keep it running a long time! )
