Colin Andrews (Single exit Spoon), averaged 29.7 mpg on the recent Woolly Bollard Tour. Considering we weren't hanging about it's quite impressive.
He was trying to maximise his mpg though.
I reckon it's down to the right foot being heavier.

But seriously, I'd convinced myself the car was thirstier with the Spoon until this meet - but clearly I was just giving it more welly more of the time.
BTW the noise down here
was awsome

It might take a while for the ECU to adjust to the difference in airflow
Been trying to find the post from recently re exhaust back pressure etc with fitting new exhausts, but no luck, anyone remember it ??
Just wondering re exhaust back pressure and engine possibly running lean and no cat especially with O2 sensor bypass ?!?

Was the O2 sensor removed and replaced to do this? They really dislike been touched and it may have failed. Worth a look. They all fail rich, or rather, give a low reading so the ECu bungs more fuel in to compensate for the percieved lean O2 reading...
