Thank you for the info. on the ECU API, As it happens my ECU is 219, interestingly, with over 4000 miles the engine seems to be pulling a little better between 2000 - 4000rpm, although it could be me just getting used to it I suppose.
I did a power run on a rolling road a few months back which showed peak power as 220 bhp and a very definite drop in torque between 2500 - 4000 rpm.
