Tuning Needed? BAD FUEL CONSUMPTION

[Sin195]

Hey guys needing help and info on what problems im facing with my S1 VT SS .. Out of a full tank of 98RON about 65 Ltrs or so ...i only get about 300 to 350Klms MAX and that is mainly freeway driving like a granny..The motor that is factory fitted is the HSV 195i ... do i need to get a tune installed (remap) or chip??? If so who can i see as i live in syd..but any idea's or info guys would be appreciated ...

probably check the air filter first. also the tyre pressures and all that.

Yeah check all the usual crap thats quick and easy to change/fix. Oxy sensors, air filters etc etc.

A tune wouldn't hurt mate. Have you changed your exhaust or anything like that? Or is it still all stock?

hey guys thanks for the replys , ive changed air filter ,fuel filter, did a service( change of oil.) and spark plugs, i have just removed the last resonator on my ss and got straight pipe just for a nice note to listen to when driving, its helped a little with fuel consumption, any people from syd do a remap n tune i could talk to?

These cars are self tuning, the o2 and all the other sensors keep things running smooth forever. If it's not running well then you have a dodgy sensor/ecu/motor/ignition/maf worn out something wrong with it. remaping it will only mask the actual problem. So it's never a good idea on a car that isn't 100%. I allways tell people, fix your car then get back to me. That's the best advice in these cases .

For you with a VT cleaning the MAF and changing the O2 sensor/s should be the first step
