fuel economy #2

Hey Ken
Thanks for the response. I've had my injectors checked twice by 2 different blokes, they seem to be OK, I guess my issue is that I live in the Adelaide hills and drive to the plains almost everyday. I've experimented with highway speeds (30k per day) and think maybe 90k's gives me the best result. I turned back the fuel as a bit of an experiment 'cause there was a bit of dodgy tear on the adjust screw, maybe someone thought they knew what they were doing, and it worked out for me. I have yet to find someone who can confidently tell me how to tune this car, or that I trust 100% with surfs. Everyone has an opinion though, and I've heard some crazy stuff about "necessary" head mods and the like. What I would like to do is get it breathing a little easier, I've heard all sorts of stuff about mandrel bent pipes and hiclones, what do you reckon the go is?
Cheers. Stevo.
