I have been running my 2 stage set up for a while now. Ive recently remapped the megasquirt and can easily achieve 30 mpg in the TVR. Not bad considering the 4.6 V8 is far from standard.
The car was run at Surrey rolling road last Saturday with suprising results
First stage is at WOT and jetted for a 75 shot at 2.5:1 ratio to a single crossfire before the throttle.
Second stage is on a pushbutton for a 60 shot at 3:1 ratio to twin crossfires in the plenum flare.

I ran 11.1 again on a much hotter Monday but this happened in the 1/4 final
I guess the 'Raceproved' shafts arent as proved as they say they are
As soon as i am back in work i will be calling Dave mac for some proper shafts.
Despite a truck ride home i was very happy after a great weekend
