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. --- _[View the full topic](https://forums.speedlife.net/t/first-700whp-tune/205049)._
