2015 Silverado 5.3 transmission settings

[Exhausted]

I selected the 87 octane tune for now but I went with the 20% throttle booster and firm transmission shift settings
I feel the firmness but there seems to be a delay from 1-2 and 2-3 and turned off torque management
Truck has 400 miles on it so is it something it needs to "learn"
It's a 2015 crew cab 2wd 5.3L
I would like the shifts to be quicker as well as firm, anyway to achieve this?

try setting the throttle boost back to 5% or so and see if the shifting feels better.

[Exhausted]

does the throttle boost affect shifting?
I really like that the pedal is very responsive

[mikel]

it can have an affect, yes.

the tune already has some throttle boost added by default as well.

Ill give it a shot, I had an Intune on my 2011 Silverado and it would bark the tires from 1-2.
thanks for the help
