SAS do advans tuning.... CRD are great you pay for what u get like if u where to buy gold you pay for what u get.. Hitman tuned my mates 200 and he worked wonders, personal preference really, most of them will have different ways of tuning sas are not really aggresive tuners from what i herd.But i dont know what sas are like never dealed with them.. Ruf performance form what i seen can do a good job for a nice price...Should give hitman a call if your after a very good cheaply tune.. But i have a feeling his over seas?? My mate with the 200 just got a new setup and matty said he was goin away for 3 weeks or so try and call if his there he ll pick up luck with the tuning fun
