if u smell fuel check ur filler cap, or where your cap screws on to, the metal thingy you stick the nozzle in when fillin up, mine was vaporising thru there.Or most likely she's runnin rich and under boost, my car was getting 270km out of a tank and on 5-6psi boost. Put the car on the dyno and the A/F ratio was reading 9.XX on 5-6psi AFM was sending wrong signals somehow, solution brought the Apexi SAFC and I was able run more boost and now getting around 400km to a tank...have it dynoed...My bro in law brought a line too and mentioned what happened with mine he got his dynoed and it turns out his was runnin rich and underboost aswell....
