Hello all,

I just bought this car and am a new Audi owner and a first time turbo car owner. I love the car and always wanted one though I have a couple of questions? when i'm running at low rpm's and I excelarate hard it sputters and cuts out some this doesn't happen all the time though enough to be bothersome. When the car goes and doesn't do this (wow) I'm impressed, fast little bugger and handles beautifully, can anyone offer some help? I have no idea where the external boost controller is or how to use it, not that i'm mechanically ingnorant I'm just not firmiliar with this set up (turbo). Thanks for any help I really appreciate it.... Below are some specs on the car, O yes and as far as codes and Cels I have no idea... Thanks again
