Zack12 Posted March 9, 2017 Share Posted March 9, 2017 I've got a 04 forester 160k miles doing 21mpg seems low but planning a remap after I've changed a few bits. Is it possible to get more power and better mpg? I'm not wanting to sound like a fool when I'm talking to the mapper Quote Link to comment Share on other sites More sharing options...
Tidgy Posted March 10, 2017 Share Posted March 10, 2017 Depends on car and mods tbh, standard vs mapped will see an improvement because mapper can lean the mix out off boost so will use less fuel. Quote Link to comment Share on other sites More sharing options...
