Dyno runs are a tricky thing. I know a place that would give 3 pulls for $75, another 3 pulls for $100. I dyno'ed for free this past weekend at a shop that just opened up, and the week before I got three pulls for $50 at a group rate for a meet. You really have to shop around, and be sure to go to dyno meets to get group rates.

My local drag strips charge $15 and $25 (Capitol Raceway and MIR, respectively) for a night of test-and-tune runs.
