OP, log your IAT before blindly changing things. Also log fuel pressure, AFR, and check tune for torque reduction. Unless you were idling the truck before you ran the 1/4, it doesn't seem like high IAT would kill the power so much as to give you a 60' time that makes it seem like you hit the snooze alarm when the tree went green.

What is the MPH? The actual number? Not a math problem (train 1 left the station at the same time as train 2, but train 1 was travelling at 25 mph and train 2 at 30 mph. If train 1's route is on flat ground and train 2's route is uphill at a 0.56 degree uphill gradient, then what is the 1/4 mile MPH of Torque BT's Yukon before tuning?).

before tuning my 1/4 mile mph was from 75-885 and after tuning my mph was a consistent mid 90’s

I put 95 mph and 6000 lbs into Wallace's HP calculator , and it comes out to almost 400 HP. Play around with it, adding your actual weight and 1/4 mph to get a closer idea of your horsepower. That's why I wanted to know your mph, to back up my idea that you are making the power, but being limited by something like transmission tuning or actual torque limiting.
