Cheers for your thoughts fellas.

I am actually getting 200 miles to a tank, and on greys with low comp and a T34 with head and cams etc I think that is pretty good!
It idles like a std car, and holds 28psi in the upper gears, so I have nothing to suspect - I was just worried about giving it some proper noise after what some have said on here..Not too too fussed about the figures, just weather it is accurately and safely mapped - don't want to see all my hard earned go down the tubes, when I can nip down the A12 to Grove garage and see Mr Bayjoo eh?!

Thanks again for your comments fellas, much appreciated
