dave's is an s3 so basically the same engine i would say you would benefit the same as him dave wanted dsg mapped so it worked out 150 quid more for both over the revo dsg software on its own so he paid £150 for 40lb/ft of torque a bargain
you will need a hpfp and rs4 valve
my ed30 stage 2+ is tuned by r-tech 364bhp - 405 lb/ft
cant recommend them enough
