Hello all,
My '04 MY05 WRX STi does around 300-350kms per tank, depending on the amount of 'spirited driving' and other such factors.
Mods are 3" TBE and Unichip ECU programmed.
I'm trying to get a higher number of km's per tank, considering removing the Unichip and reverting to stock ECU. It just seems to use so much fuel, even when just cruising on cruise control along the freeway in 6th .

Interested to see others kms per tank numbers.
If you could list:

Car Desc:
Mods/boost (psi or bar)/kms per tank

MY05 STi:
SS TBE, Unichip/19psi/350kms

was the unichip programmed after the tbe was installed?

Hi, got 03 STi, MRT XB Kit (3" TBE, Fuel Pump, ECUTek, CAI, GFB manual boost controller @18Psi 209awkw) getting 10L/100 on hwy, combined driving around 11-12l/100, town really depends on how much juice (can be over 19L) but usually around 14-15L.

If it's tuned well then fuel consumption for same performance will be better. If you are regularly giving it a bootful then you can expect much worse fuel figures. Mines tuned specifically for a leaner mixture on partial throttle between 3000-3300 for the 110-115kph 6th gear cruise.

Hope that helps.

Yes.
Wow when I did a search for the terms "fuel" and "consumption" it came up with none of the threads I now see below.

400kms if i drive like a granny and about 200kms if I am having fun. It usually averages out to be around 11.8ltrs/100kms everytime I fill up

maybe worth removing the unichip and going verso

I'm wondering whether the stock settings would prove to be more efficient over verso?

why did you go uni chip over verso? Did you buy the car from over east or something?

My version 3 RA makes over 300hp atw and im still on my tank from the memorial cruise which was 150ish km of full throttle action and had a very spirited drive home from work last night and a few other trips here and there and i still have a quarter left with over 250km on the trip metre, i usually get 350ish out of a tank...i think my consumption is better after my recent tune as the fuel was turned down a bit but im making 30 more kw at the wheels...

Get the uni chip retuned or pull it out and verso

would have thought going for a verso tune would be better. can be tuned taking into account the 3' TBE

Bought the car with it, also found the thread I was looking for!
