There is a difference between throttle closing and throttle limiting.

Every stock TCM tune car I have delt with so far was this way.

Here are some screen shots of my brothers 2019 A10 ZL1.

1st pic is basically stock with flex sensor and stock TCM tune. 1st and 3rd gear limit throttle at the bottom of the gear.

2nd pic is with headers, cai, 95mm tb, E50. It's getting much worse. pretty much all of 3rd is limited to 50% throttle and even 4th just a little.

3rd pic is all in. Ported Blower, 2.1 pulley, cai, 103tb, fuel system, E50, TCM tune. Throttle open all the way in all gears. The car 60-130's bottom 6's and traps over 135 full weight on 20" forge lines.

Mine was exactly what the first pic shows. On all runs.
