how much??

That sounds about right. Most shops charge about 50 bucks an hour or something like that. Dunno if it includes tuning or such, really depends on what shops you goto. Usually it would cost a bit more, like around 600-800, depending on work and the skill required. Labor is not cheap man.

shop near me charges $65 an hour. usually the only tunign they do is making sure there isnt any problems. real tuning with a dyno and such can run you up to about $1,000 for a full day of tuning.
