I usually use Pettit Racings dyno, that is where I tuned last time. But, we discussed using MacDonalds dyno, the only thing is every time I have been there, there have been rotary specific issues, he also like to make the pulls and he lets out about 2K RPM too soon because he is used to Fords with their 4.5K redline. ;)

Where are you located, I'll ask my mechanic if he is interested in giving you a try.

Have you ever had a rotary on your dyno? For some reason Dyno's get upset with then and their wasted spark coil pack arrangement. They get all confused.
