IMHO it's not so much the gearboxes fault that economy isn't mind blowing as standard... I had a OEM DT box on mine with the GT20, and 55mpg on the motorway was pretty common, sat at 2750rpm at 70mph... 80 is 3k.... I could get 60mpg if I sat at 60mph...
If you want to make it efficient, get a more modern turbo.... Less boost =/= more economy
