Here is another problem I have been having, and I really have no idea what it is from. Spontaneously the RPM Tac/Powerband (whatever you would like to call it) shuts up while the car is still running and then the TCS or Traction control light turns on. The only way to reset this is to shut the engine off and restart which i hate doing. The car still runs fine and I can still boost but am curious if anyone knows anything about this. If so, Please let me in on the secret!! Thanks, in advance, for any help anyone can give me!!
