my hj61 runs 35's and it actually gets better fuel economy on a trip when it's loaded with my camping gear rather than empty and mine does just over 2100 rpm at 100kph, the reason i ask about injector pumps is my brothers ( the auto ) seems to only rev to 3500 rpm even when you hold it in gear and mine will happily rev to about 4100rpm. I'm not sure if it was designed like that or his has some other issues, either way i think the manual is superior.
