Fuel Economy R34Gtr

[sinistaGTR]

Hey guys, just wondering what sort of kms people are getting from there 34gtrs. I have full exhaust, nismo panel filter, power fc and 1.2 bar boost making 245kw. I'm only getting bout 300kms out of a full tank and that's with half highway kms. Does this seem normal???

Might need to improve state of tune & check AFRs

Previous Black R34 GT-R > 460-470km/tank stock with 3" exhaust/hi flo cat and HKS F-Con V-Pro 1 bar (228awkw)

Current B/Blue R34 GT-R > 390-400km/tank with -7s, 3" exhaust/hi flo cat, cams, gears and PFC-D-Jetro 1.5bar (300wkw)

it really comes down to how you drive it. if you give it the beans on a regular basis then your economy will be much worse than someone doing the exact same trip as you but driving more sedately.

400kms around town, 1.2bar.

On the highway, up to 600kms.

MAD082-Nah even turning the boost back to .7 bar and driving very sedately its still churning out black smoke and chewing the fuel. Even my mate commented when he was behind me in his evo in traffic at how much it puts out.

Thanks Sean for that info.

if it's pumping out a decent amount of raw fuel then you should definately get it looked at. could be a tune issue, or a mechanical/electrical issue causing it to use extra fuel. may be an issue with the AFM, injectors, fuel pressure reg, TPS or a few other things. best to try and suss out if there is something wrong before simply getting it tuned, because if something is starting to fail then it may get worse and then when you fix it the leaner tune could make it run too lean.

370rwkw, PFC, stock cams and NO O2 sensor. Strictly off the tune.

650-700km on the Freeway

250-450km around town. Depends on right foot as once on boost, its destroys fuel.

340kw, PFC, 2530's, etc
