What is a fair cost for a good dyno run and tune?

 

$400.00 for a custom map, be sure to tell the tuner you want the map burned to cd.

 

That's about right.
Cost me $375 for mine.

 

You can get a custom MAP for $225.00 here in Maryland.
Itis $75.00 to load test and if you need a custom MAP its $225.00. $75.00 gets credited.

My base MAP tested fine, so it was only $75.00. About 45-60 min dyno time.

 

$300 at a Private Shop out here in Arizona. The dealer wanted more[:-].
