De-tuning a xud for economy?

[Andy annear]

Ok, I know this is a gay thread, but I seem to be spending all my time filtering WVO atm and its starting to grind... Currently tuned to 'stage one' 18psi, and down to about 36 mpg driving very steadily, this seems pretty low to me?

So my question, what do people remember to be getting standard from a bosch'd xud? I m running 100% wvo so pointless having it tuned as she wont pull smooth all the way through the rev range, so this weekend i wanna put it back to standard, or could i go below standard to get epic mpg's???

Cheers,

Andy
