If your only getting 250km's per tank around town russell, than you either need to lay off the right foot or find a better tuner.

Even my 1966 xr with 750holley'd 351 2V clevo pushing 504hp thru a c10 2500hi stall'd, 3.5 diff gear'd, got a lot better than that around town.

I'm currently running a 320,000km's AU1 V8 with crow 1317, 1.7 rollers, 180seat pressured double with damper, 30thou off heads, ported tb and top intake, k/n panel filter, pacey 4006's with twin 2.5, standard gears and stall, and mine gets minimal 450km's per tank and at best i've gotten 900km's to a tank.

Now before any mod's when i first purchased the car on standard ULP i got 600km's to a tank long trip.

In saying that my tune at the moment is very lean, 13.4 average full throttle, 14 to 1 over 4000, due to a poor fuel pump, and lack of a tune. But my cruise mixtures are at 14.7 stoich when ment to be and my lean cruise is 17 to 1 like its ment to be. And if i got a tune done and it got worse economy on a cruising trip long or short, i'd be really pee'd, obviously full throttle is a different story.

really these days, where does one draw the line from being a tossa flogging their car everywhere to someone driving their car nice to obtain better fuel economy. The world is changing with oil prices and some of us (me included) need to take notice.
