right lads im only getting 60km out of €10 of petrol. Thats 240km out of a full tank. And i dont be racing around the place thats just cruising and motorway driving. Seems to waste the same still if im using turbo alot.

it has a decat,full exhaust, new iridium plugs new rotor in the dizzy just serviced a few weeks ago

any ideas what could be causing this?

i know it sounds stupid but mine blew an injector seal randomly once and drank fuel, well it actually pissed it every where but not really enough to seem anything more than unburnt

a drop in compression would cause poor fuel consumpsion, check your compression on all four

just thinking if you have an rrfpr or similar she could be running very rich.:freddy:

i have ported mani,autobahn decat,apexi catback,autobahn front mount intercooler,front mount air filter, hks actuator think thats it!dont have rrfpr by the way

runs okay to .7 bar but not boosting past .7 bar cause it hesitates could be fuel related too?

well I have same mods as you except the FMIC and I had to install an RRFPR to support 13psi otherwise there would no way be enough fuel going in.

They say you need to up fuel pressure from 2.4 to 3.0BAR when running 1 Bar of boost, so I am thinking perhaps the ECU is extremely confused...get an RRFPR and turn up the fuel to support your extra boost ability.

I know this sounds illogical as you are using 'too much' fuel, but looking at your description of mods etc I cant imagine the engine would be running correctly on standard fuel pressure anyway, and ECU has strange tendancies to make up for it...

You dont need an aftermarket FPR at 0.7 bar mate, and ye any more boost and the stock ecu will get real rich thats why you feel a bit of hesitation up around fuel cut.

Try doing a diagnostic check see if it brings anything up, could be your lambda sensors fucked or sumat.

You wont need one if you are only looking for .7Bar however my understanding is that you are running more than that but it CANT boost past .7 hence a problem? 2.4Bar fuel pressure simply not enough when running much more than standard boost.

The ecu will fuel up to fuel cut, at 0.9 bar or sumwhere around there, then the ecu will cut the fuel to prevent the turbo over boosting. If hes looking to up the boost to 1 bar, which would should see a nice improvement in power, then yes he will need to buy a FPR, as well as a FCD.
