Can't tell you, Dave. I have only owned and used a Dynojet. Probably that's what it is, weren't so many out there twelve years ago. On cars with lock up converters I would (for only a pull or two) lock the TCC and roll into the throttle slowly just off idle to take the flash out of it.
Any chassis dyno will not give accurate numbers due to converter slip. Especially below the RPM where the converter hits. If you can make the torque numbers bigger there, you helped it. Just still won't know your torque peak RPM.
Street cars with, for example, a 2800 converter and a torque peak around 4000 will show it OK.
Stick cars get more usable data on a chassis dyno.
