s3 tuning opinions and options.
right at the end of the month the s3 is getting garaged for the winter, as a daily driver its fast aproaching 83000 miles. its got the amk motor, its got a ****ty map, a milltek cat back, n249 byass, green cotton replacement panel filter however im getting bored. it seems to run better in cooler conditions and i would like it to be a bit more of a mind blower. now i dont want to spend silly money but i definately want extra bhp. what would you or what have you done? any replies will be appreciated.
