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
