Have your ECU remapped by a reputable tuner.Also known as chipping,choose a tuner with a long history in tuning Audis,not one of the raft of "fashion tuners" that have popped up over the last few years.

Hi JamieLee, welcome to the forum. Have a browse through some of the older threads, yours is a popular question and there are quite a few options. I am no expert on this but a number of our other members have recently made some pretty good upgrades. Take a look at the following links for a start:

Hope these give you some pointers.
