Ok Sigma boys lissenup !
Ecu remap update after 1000 miles:
More power evident in all gears and revs smoothly from lower down the rev range; 2nd in particular is transformed and seems to now have an additional surge above 4,500 revs.
Fuel consumption just over 48 mpg on a mix of early morning 'spirited' runs and daytime commuting around Bristol.
No downsides !
Cheers
Jeremy
