Dyno question regarding gearing and accurate readings

[Whiteybird]

Recently had my stinger dyno'd, but the tuner was unable to get a full pull in 5th gear, due to it downshifting to 4th, then short shifting in to 6th. It was in sport, with the paddle shifting activated.

Do I need to have traction control/stability control disabled in order for manual mode to stay in 5th for the full pull? I'd like to get an accurate reading the next time I'm on the dyno with my new mods.

The car is a JB4 equipped 18 GT2 RWD. @Terry@BMS any pointers?

Correct. You need to have all the nannies disabled. Also let your tuner know about the pedal switch. If you press the gas pedal all the way down you will feel a click, that is the pedal switch, it will make the tranny down shift, even on sport with manual activated. Your tuner needs to not press the gas pedal all the way down, just enough to reach the pedal switch without pressing it.

Also the tuner needs to let off at or before 6500 rpm otherwise it will upshift by itself.
