Good morning all,
Any one have any idea as to why my fuel consumption would have increased dramatically? - measured as litre's/100km.
** A little history first **
- I have a 2016 SR5 auto, had a remap and 3inch exhaust last year and fuel economy went down from 10.7 avg to 8.5 avg, loaded up or highway
- Recently installed ARB Frontier long range tank and fuel economy didnt change - stayed around 8.5
- Just had 90k service with a new steel bar and winch fitted with new front rotors and pads
- Car now seems a little rough at idle or just off idle (when rev's are coming down stopping at lights etc)
- Otherwise no other noticeable change other than economy going back to 10.5 ish.
I have no idea and before I take it back to my mechanic I was hoping to maybe get some idea or check a few basic things.
Would a re-map disappear??? and reset to factory ???'Surely the bar and winch wouldn't impact that much ???
Thanks for any suggestions. Simon.
