Thats terrible!!! First thing, how did your remap? Did you have a propper remap done on a rolling road etc think they call it a dynamic remap which means its done to your car. Or was it a plain plug car into computer and press button to increase power?

Also when was it last serviced? Is your temp sensor ok? Have you got any boost leaks? Have you had your car scanned?

How are you driving it?  I can get as low as 14mpg but on the other end of the scale I can return 36mpg

That also doesn't sound too bad to me depending on driving style. Mine averages 27-28 but I'll see 35mpg on the motorway and 15mpg if I'm having a blast.

when mine was healthy I could get 42/43 on a motor way sometimes up to 45/46 if the journey was long enough. Around town, I tried not to look, but was around the 25 mark.

i'll get 200 to half a tank but thats because im a cruiser  :drool: though a remap should be a bit better than the standard map sure your not just planting your foot because of the remap?

yes got it on a rolling road. i fixed the hose with the leak got a new MAF, N57 sensor eveything was ok after that, got it put on the rolling road and the car wasnt boosting at all. so the guy when in to his office with a USB done sumthing on his computer plug in the USB in to his laptop and run the remap. run the car and it went from 150 BHP to 185. i ask him what did he do, he said he changed the setting for the boost. took the car for spin and near crashed lol. i didnt realise the fuel consumption would as heavy as i thought.

shouldn't be that low unless your ragging it about

have you checked hoses under the inlet manifold for leaks and does the coolant temp gauge stick at 90 when warmed up?

I've just got 300 miles on £60 and averaged about 25mpg. Mines over fueling and I can smell it. Anyone know what could cause the over fueling because the mpg is sh!te!!!

I have not checked hoses on mine (yet) and it stays on 90 when warmed up, what does this mean?
