Is this a record
 

In my mates RB5 I managed 372mls on a tank of fuel and the light was not on ,He looked at me in disbeleif when i told him :D
The as a tek ecu and is decatted.It does seem quite good though:D

best check the maf sensor ;)

have stretched about 330 without light in my decat rb5 doing a roads at 65mph (commuting 35 mile round trip)

I was going for 400 the other day, but I got bored at 280. I think it's possible though if driven carefully.

jesus, I manage about 180 - 200 :D

150's my worst on the road :D I usually get 200-220

I got 360 with no light:) Tek3, full decat, k&n etc :D

Running lean though :eek: one new maf and one new lambda later and all was well :D

Whats the MAF got to do with MPG?

It underreads when shagged. ECU thinks there's less air flowing than there is , so doesn't introduce enough fuel. Engine runs lean.

Thank you :)
