Finally got round to booking the motor into Awesome, taking advantage of their Black Friday deals and some time off work.
Results - 351.5bhp and 338 lb/f. Have the graph saves as a PDF, need to upload it.
Initial impressions, wow! Why have I been driving a stock one for the last 6 months? Pulls really hard through the revs, sounds amazing and no noticeable drop in MPG. Winner!
Fuel pump into 2014 to '+' it I reckon.
