Hi guys, i just got a 2.5 Lukey exhaust system and pacemaker extractors instaled onto my TL and im finding that my car is using twice as much fuel as before. Any ideas on how to fix this problem?

Are you driving the car the same way? Your probably excited with your new mods and are giving the car alot more. Three times as much would equal like 30L/100km on your trip computer, which is a figure you could achieve probably only on the track.

Ive been driving the same as before i had the mods done

Whats your read out on your trip computer of average fuel.

15L to 100km

15L to 100km

It's not using three times as much. Around the city the best I can get is 12 with a stock car. 15 can be expected driving heavy footed.

I would be checking that the O2 sensor is still hooked up. You will find it after the extractors.

Yep I would say 02 sensor if anything. But 15L/100km isnt too bad for heavy foot/city driving. I know my economy is up around 17/18 with awd and all city driving lol
