What carb and diff do you have too!

I'm asking because running LPG kills a bit of my mileage, and i'm wondering what the best can be.
i'm up to 16ish now around town with 700 feet between stop lights and a drag race at every green... people here drive craazy!

Around town numbers mostly, I can get 33mpg at 75mph and still get disappointing #'s in town.

Currently I know my issue with running lean has to do with the amount of hot water my vaporizer is getting, otherwise it wouldn't be perfect lambda all over town and then get lean after a bit of highway driving, then run rich after sitting running for a bit to build up heat, then go back to lambda again.

Whee! modifying everything is so exciting!

other fun things, moving intake a bit to prevent the 90 degree bend from bouncing and making things stuff up. It seems too, that having too short an intake can be trouble too, i have a cone filter on the vapor mixer and a 90degree bend intercooler hose to the throttle body. I think one of those k&n cold air filter pods would fix that right up... never seen one... they're pretty cool.. k&n apollo

...hmmm why don't the built in image tags work?
yeah... best around town mileages, reasonable #'s over multiple tanks of fuel.
