MPG and boost control

[Davezj]

here is a little bit of info i found out recently.

i had an EBC connected in and had it set to 7 psi with no start psi so it should be working like the normal factory boost control.
on a run i got 22mpg motorway miles (manchester to york) doing 70mph ish
i remove the EBC and fitted the standard factory boost control
on a run i got 29mpg motorway miles (manchester to birmingham) doing 70mph ish

now in my opinion the difference is too great just to be different driving conditions.

however manchester to york is the highest motorway in the England so it is up and down over the mountains.

what do you think

If Manchester to York is more up & down mountains I would expect to use more fuel cause your having to put the foot down a little more to climb the hills.

i have a mbc set to just under one bar .
i travel a twisty bumpy road for half my journey to and from work the rest is average b road ..
mixed driving and manage roughly 27mpg.

sorry thought you removed it for the return journey from york

[Davezj]

no 2 different journey's unfortunately
but the difference is massive, 7mpg is hugh amount

Sell it , get a diesel.

You can't compare 2 different routes. No point in even speculating on possibilities until you do a fair test.

[Davezj]

true it not a fair back to back test, but that is still a massive difference.

i will have to do a more comparible test next i go home to visit parents

[Wobble]

head wind and tail wind can cause a large difference also. just a thought

[lancerevo3]

true if thats the difference on a back to back test it would be worth investigating.

p.s shame on you for having your b.c set to 7psi
