Running rich? (98 octane)

[rhodieee]

Hey guys! My RVR is sitting on 15psi and normally costs me 75-85 dollars to fill up with 98. Depending how much is fuel. So pretty much around town gets me 250km that's including every time I turn of the car I set the turbo timer to 2 minutes for the turbo to cool down. (my recommendations). But on the highway I get up to 350-400km. I do like pushing the car around town for the sake of the BOV and at red lights. But was really wondering if people get the same KMs in there RVR or is just mine running rich?

On eflex I get 600km on the freeway & about 300km around town.

2 min turbo timer? Lol.
Just drive it easy for the last few kms home.
Bov will also cause you to use more fuel...so if your worried about economy get a plumb back.

Cant tell without a wideband. Your car may not be even running in closed loop.
also check timing, every bit of advance you can run at cruise will save you fuel.

Hey mate, prior to exhaust and intake changes I would get around the same.
Following changes (3 inch exhaust and straightened intake with 055 MAF) I get around 330km around town and 500km on the highway.
My advice is to let the thing breathe if you haven't already. Further to that, clean your MAF as well. That can help too.
These rigs are a shit aerodynamic vehicle......

My standard auto SSG always does around the 350k's mark.... Ive had 5 of these cars and that's about the same as ive had on all of them... But im definitely keen on trying what White Knight said tho

Read up before you clean the maf. Plenty said about it wrecks the maf.

You can stuff them pretty easily. However its pretty straight forward though. It did help mine out a bit.

Exactly ditto for me except I drive it like a granny trying to stay off boost.(It doesn't make much differnce to mpg)
I think I may have another turbo leak by the sounds of it
