2008 Suburban LTZ 4x4.
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.
