i done a 330mile round trip on one full tank of petrol and my car is running 390bhp kept it at 3 grand doing 70 mph with no boost and thats what i achived, i was really please with this but what do you all think is this a good or bad

 

Very good!

 

Wow. I'd say that is extremely good.

 

good, done near that myself on a long m/way trip , but it gets a bit boring lol.

 

Where did you pick up the AA truck?

Only joking that is very good.

 

yeah it was all motor way miles apart from about 40 mile of it i yes i was very shocked my self but i did fill her right up to the point of petrol being visable in the filler neck i guess it could be down to the mapping to some degree

 

About 25 mpg, i dint get that on 315 miles one way trip last yr. I got 24.5 but only had 240bhp full loaded car.

 

I get 250 miles to a tank (£58) of town driving which os about 21.5mpg so not that bad imo

 

thats brilliant ive got 215bhp stock turbo 2k. and i only get 310 to a tank normally.

 

I managed just over 200 miles on half a tank.... Manchester to London last night.... Probably due to the 40-50 mph average I was doing along the M6

 

I once had to refuel on the 175 miles journey from Huntingdon to Preston, back when the A1 had loads of roundabouts. Set off with a full tank and good intentions but boredom set in after 30 mins

 

I managed on a clear run on the m6 / m1 - 30mpg. On the way up north, same roads but a bit of traffic and overtaking i managed around 25mpg.

Thats on a remapped blobeye - 280 bhp ish i think)

 

Whats the best RPM to be running at on a motorway to get the best fuel MPG?

 

my car seems worse on fuel since it was mapped...it also stinks of fuel if you stand behind the car...this normal?

I got 18mpg with ECO driving around town.
