Running the duel dawes setup has a bigger advantage on a vehicle with quite a quick spool rate, I used too run a duel dawes system on my last patrol and running the low boost at 10psi max around town saved more than 1ltr-100. I found running the higher boost setting on the freeway had a better fuel consumption then the low setting.
I have a single dawes in my troll now set for 18psi max and have the spool almost spot on.
Drove too trarlgon last week and averaged 11.5ltrs/100.. Not bad on 33's with 2" lift and roofrack
