MPG reading help

[GTV]

Just been checking my MFA MPG reading and its a bit highter that it realy is, first things first people how have MFA's how accurate do you thing the readings from it? also is there anyway to ajust it? I know on my old Mondeo there was a way to get into the settings and ajust it for a better reading.
Cheers.

The MFA's are known not to be accurate unfortunately and as far as i know there's no way to correct them

I have know idea buddy.

Best i have ever seen it read was 42 on my 16v and before i put the boost valve on the 8v i could get about the same but since putting the boost valve on my misses says it wont do more than 28 so it must work a bit i spose...lol

Mines out by about 2% with normal driving, if you hammer it then the amout its out by increases.

Achieving about 43mpg on the MFA, 40ish in real terms.
