Are you looking for roller dynos only? Or anything as long as it's before-and-after comparison (as that's all that really matters)?
The dyno place I go to and trust (ever since I was still tuning my MR2 turbo) is Aggressive Performance in Santa Clara. It's primarily an MR2 shop, but the owner is my personal friend and for sure will take care of you. I believe he hiked up the rates since last time I held a dyno day there for a few cool cats in the bay area, but no harm in contacting him and getting a quote
