How repeatable is Gtech Pro

[DeadOn]

These things use accelerometers and I know they need calibration. If any of you have these, can you get repeatable torque readings run to run? How repeatable are they, within +/-?? ft/lbs??

i dunno i went up a hill and got 500 hp and torque.....

The new G-tech pro competition has auto-leveling. It's a nice unit. I'd save the money and dyno though unless you want an extra toy to spend $$$ on.
