I use BP Ultimate, when i get down to just above a quarter i have about 270 on the clock and this is while driving normal, no thrashing. I got the car tuned about 6 months back and everything was fine, i was getting this same KM amount even before i got the car tuned. I don't really want to let the fuel get to almost empty, so i'm thinking i would get around the 350 mark if i almost let it go to empty.
Could it be my 02 sensor or AFM?, or do the KM sound ok?
thanks
the mods i have are:
PFC
FMIC
3" Turbo exhaust
11 pounds
Pod CAI
also got some irridium spark plugs put in
