I know my N/A likes to drink when I floor it in 1st, so I don't, and haven't in the GT either. It has hit full boost only a few times in 2nd/3rd year, I'm a student so can't afford to piss out fuel lol believe what you will 50 miles to £10 sounds pretty shit to be honest, I remember reading a thread where most of the Turbo owners said they were getting 30mpg+ even on TD04s It that 75 miles to £10 Spark? Or 75km? The thought that it's running rich did cross my mind, my mate's Auto GT smells the same and he's definitely running quite rich (black smoke)! I didn't think it would run rich without a RRFPR though? I thought it would be lean if anything with the ECU alone Yeah that's exactly how I've been testing the car, how I would drive it day to day and I can honestly say that I won't be able to run this car if this is what the consumption will be like from now on I dunno about piston rings, there's no dodgy noises or any smoke whatsoever, the engine seems to be running sweet bar this fuel issue! Thanks dude that's a good idea about the timing, I don't have a timing gun myself but I could get it checked I suppose! I've actually filled up twice to £10 and first time it did about 75km, so it's pretty consistent. I know the car did do around 250 miles to a tank though when we first bought it, but it was completely standard then and in dire need of a service! I know what you're saying, but the fuel gauge doesn't drop when I let it warm up, the idle is not very high and surely it wouldn't be sensible to start driving a GT Turbo from cold??
