range from a full tank of diesal

My understanding is that remapped should get you higher mpg as car computes levels more frequently making it more efficient obviously taking into account the levels of tuning. From most things ive read the 170's always seem to do more thsn the 140's

I average 502.6 miles a fuel up, or 44.8mpg.

This is exact calculated via fuelly, NOT mfd. Standard CR170

To be exact

Just so people can get an idea for comparison can people list their model and bhp, along with clarification if readings are calculated or from the trip computer

 

[Jarre]

To be exact

Yep

 

[tony323ci]

Mine is based on the exact mileage I declare for work

 

[STU3Y]

Short jouneys don't help I do mostly motorway miles and regularly get 600+ from a full tak down to fuel light
Very happy at that and I am remapped too

How long are your journeys on average?

 

[tony323ci]

How long are your journeys on average?

usually 150-160 miles each way in the same day and get two trips like that from a tank giving me around 600-640 miles to a tank
I have google mapped the routes too and mileage is accurate

MK2 170 got 540 out of my first tank in the car last week, 70% motorway but so much traffic its a joke. Spent around £120 to get 950miles so far, getting more used to the car so MPG is going up

 

[STU3Y]

Just getting my car terracleaned. Only time will tell how well it works. Not expecting a big difference as I only have 35k, however mpg is low so thought it was worth a go. It certainly won't hurt.

 

[STU3Y]

Well terraclean done, not really been able to do proper test drive as had to go back and pick up the mrs' car which is getting done any min. My findings so far:
As soon as it started up I could hear the engine sounded quieter. Felt alot more free revving. On pulling away it revved quicker more responsive, a bit nippier. Coming on and off throttle is alot smoother too. Only done about 2 miles so obviously dont know about mpg yet but will update when the tank is empty.
Heres a pic of the pipework hooked
up

Well got a 1/3 left in the tank and it's gone beyond the predicted range of 390 now on 450, will see how far i can stretch it. In terms of the types of roads pretty mixed really between short 30 min drives to a couple hours along the motorway.

STU3Y that does seem a little low, i've had the consumption figure on the display and urban i'm getting low 40's and motorway around 55 @ 60~70 and 51'ish when I was doing 80

Just reading about terraclean will be interesting to see what effect it has for you

 

[STU3Y]

Just did a couple of miles round town and even my girlfriend was shocked by how much of a difference there is, turbo spools quicker and kicks in alot harder

 

[STU3Y]

Today I refuelled for the first time, previously i only got 420 miles til the fuel light came on. Got 462 this time so 10% increase in miles per tank.<br />
Mpg figures have increased from 36 to 41. Figures calculated not taken from trip meter.<br/>
