Had my car at Sodex Performance in Sunderland for a stage 1 remap on Saturday morning.
First run before the remap car was making 246.3 bhp and 386 ft/lb of torque.
After the remap the car made 291.3 bhp and 475 ft/lb of torque.
First impressions are that the throttle response is much improved and that the car pulls stronger and smoother for longer in each gear. Mid range acceleration is back to what i was used to in my previous car (BMW 335d).
Only done 200 miles since the remap, but if the fuel computer is to be trusted it looks like i have also gained some not insignificant economy improvments.
All in all it would appear money well spent.
