The tittle says it all...

 

depends on tuner, between $100 and $200 per hour.

 

400 dollars flate rate over here in my neck of the woods

 

Ill do it for 10$ an hour, but i guess you get what you pay for....ha. To the OP what kind of question is that. What do you want tuned? What do you want to tune for? I guess if you really wanted to you could spend hours on a stock motor on a dyno and tune it for max gas milage or max hp or max money you could spend with out doing much of anything. Why don't you ask a shop, you would probably get a better answer.
