i'm all over the place trying to figure out why my bro's a6 is so rich, but research and knowing a few buds w/ these cars lead me to believe they begin to run rich after they acumulate alot of miles.

if all else fails, anyone ever put a vacume canister inline w/ the map sensor? i read where the guys running itbs use them cause of poor im static pressure.

i think it would cause the map to react slower and that seems like it would fix my problem (u press the gas and it always smokes up then chills once u ride a constant rpm)

thanks
