GT350 DYNO tips?

[Zitrosounds]

For those of you have have extensive time on the dyno with a 350, What tips can you provide? I ran my car on Saturday during a dyno day at my local tuning shop. We disabled advancetrac but the car still exhibited some hesitance like it was applying brakes. It also threw I think every light drivability warning availiable. For example, ABS , drive modes, exhuast modes....I think the car was confused that the rear wheels where turning and the front provided no signal.

Is there any special trick or settings to run on the dyno efficiently?

Thanks,

Harold

Did you turn it off off? As in the hold the TC button down for a slow count to 5, off?

I dyno'd mine in Track Mode since it turns everything off and it went fine.

Hold TC switch for 5 seconds to disable stability control/TC before pull.

All the lights going wonky after dyno pull is totally normal. WHen your car does the equivalent of a 140mph burnout it's going to be a bit confused. Drive it for a block and everything should reset and go away.

I completely disabled AT with the long press. Tried Track mode and no worky. All the faults did clear up after a short drive. Becuase the car was shut off and still on dyno for a second run could not reset the warnings or switch modes. Oddly enough on the second run the car made more torque and less horsepower with the valves closed on the exhaust. I don't know if it's due to the valves being closed or the car being warmed up but I thought it was interesting
