Donald My 4/4 sport seems to go v well. am sure the ecu has an adaptive feature.so keep booting it and the ecu should change,
My car has a sports exhaust .... Maybe that helps?
Am going to fit a K&N kit ....but only for fun...she goes well as she is.
The best mod is the 4.1:1 competition back axle ratios......makes the car feel a lot more responsive.
