Not bad at all, nice to see you're doing your bit for climate change!

How much gas does it use at the same time?

Is this figure from the computer?

Vindaloo - Only did the runs sunday using my Toyo t1-r tyres. I really want to find some big-*** slicks to use. I had my toyos down to 15psi, but it actually made it slower from 60mph and up.

Alex - off-boost it barely uses any lpg - This is purely down to mapping and the big turbo.

Tonto - Yes, it is per computer and I don't expect 70mpg all the time. However, as I've been consistently getting 600 miles to a tank (and not even with 45 litre fill-ups) I'm pretty confident my computer is fairly spot on. It's at least 60mpg on average - this morning's run was exceptional - a few favourable green lights.
