kfmotty88 Posted November 2, 2015 Share Posted November 2, 2015 Hi I have a subaru impreza hawkeye wrx and my mpg is to be said at 16-18mpg if I remap my car how many more mpg will I get? If it's just like an extra 4 or 5 I may aswell wait Quote Link to comment Share on other sites More sharing options...
Jay762 Posted November 2, 2015 Share Posted November 2, 2015 Is it a standard car - do you use V power or equivalent? you should be up around 24 - 28? But if you get it breathing properly with a less restrictive pipe and a panel filer you shoudl see some improvement as the engine will be flowing a littel more freely Quote Link to comment Share on other sites More sharing options...
Tidgy Posted November 2, 2015 Share Posted November 2, 2015 why do people talk about stages, what complete rubbish. anyway that said, is it a full custom map? Quote Link to comment Share on other sites More sharing options...
stants Posted November 2, 2015 Share Posted November 2, 2015 why do people talk about stages, what complete rubbish. anyway that said, is it a full custom map? Depends where your coming from I suppose, vag, vauxhall, ford, those boys tend to break it down into stage 1,2 3 panel filter, map, then something else after, Maybe it's easier to describe to their mates down maccy d's [emoji23] Agreed that low mpg needs addressing, maybe get it on a dyno before you decide to upgrade to see what it's doing and if all is working ok Quote Link to comment Share on other sites More sharing options...
martyc Posted November 2, 2015 Share Posted November 2, 2015 Around town, short journeys or heavy foot = **** mpg. Check your driving style first before you assume there's a fault. That and a good service will make a difference Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
kfmotty88 Posted November 2, 2015 Author Share Posted November 2, 2015 It's just had a good service. And it's a standard engine. Got my figures from tech spec on autotrader tbh. I'm using premium unleaded fuel, just wish she wasn't as thirsty ha. As much as I love the car it kills my bank ha. I don't drive it like a nutter either Quote Link to comment Share on other sites More sharing options...
Gaulson Posted November 2, 2015 Share Posted November 2, 2015 That's true, my normal driving was getting me 260 - 280 a tank. I'm driving a little different, shifting sooner is the main one and i'm hitting 280+. Not quite managed 300 mainly because I haven't wanted to get too far from a fuel station haha. On another note yes with a panel filter and different exhaust you should see better mpg but as to how much better it's anyones guess.

kfmotty88 Posted November 2, 2015 Author Share Posted November 2, 2015 Well I read about getting your subaru remapped gives your better mpg I just wondered if this is true and is it actually noticeable Sent from my SM-G925F using Tapatalk Quote Link to comment Share on other sites More sharing options...
stants Posted November 2, 2015 Share Posted November 2, 2015 Yes it will give you better mpg, before map I saw 21-25 mpg, I now see around 28-30 even higher if on a long motorway run, get around 330-350 form a tank (classic size) now too, You'll get more horsepower more torque and increased mpg, Mines paid for it's self in fuel saving in the 10 months since I've had it done 1 Quote Link to comment Share on other sites More sharing options...

Tidgy Posted November 2, 2015 Share Posted November 2, 2015 Run it on vpower or tesco 99, not just super. super is typicly 97 ron. rempa gives better mpg becuase off boost they are normaly very rich from the factory and and can have the fuel backed off Quote Link to comment Share on other sites More sharing options...
Jay762 Posted November 4, 2015 Share Posted November 4, 2015 I know mines not a turbo but the Tesco 99 gave a noticable difference in response and mpg compared to Shell vpower - was not as good so I try and use Shell where possible - will be trying teh BP excellium in a bit see how that compares Quote Link to comment Share on other sites More sharing options...
