The only thing I dont like about J&S mustang dyno is that its speed pickup is RPM based matching with vehicle speed… Basically you set it at like 3000 rpm or something like that. You get the car running about 3000 rpm and then match the tach onthe dyno to that rpm. I think thats how they did it. There was no plug wire pick up like a dyno jet.

I agree… that is a terribly inaccurate way to compare a cars before/after modifications on the same dyno, they really need to get the RPM sensor working.
