Remap stage 1 question

[kfmotty88]

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

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

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

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

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

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.

Well I read about getting your subaru remapped gives your better mpg I just wondered if this is true and is it actually noticeable

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

Ok thanks ☺

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

[Jay762]

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
