went saturday to SCR and pulled off a 1.66 - 11.81@112 on NX 100 shot it was still spinning some couldnt hook all day was pulling 1.76 - 1.78 then got a 1.70 and back to a 1.78 then to a 1.66 after a 1/4 lbs drop in air pressure in the tires. so 1.66 with 12.25 psi in tires. im not sure why its not faster, but my consistant motor times are 12.7 both times ive been its been pretty warm like 70* or higher and DA has been 1300+ both times too. How much does the weather/DA affect these motors????? and i only trap 103 on motor

weather, temp, humidity, and DA play a HUGE factor in your trap and e/t... these motors can feel like two different powerplants on two different days just with a weather change...

There are two main tables that can pull timing one is based off of your IAT temps and another is based off of ECT temps. Stock tables will start pulling timing at a IAT of 80* ( 86* = 1.1*, 95* = 2.5*, ect) and an ECT of 198* (203* = 1.0*, 212 = 1.5*, etc).... On my tune I bumped that up a little bit because when your truck is warmed up ~198* your PCM is set to pull timing.... I am sure you tuner adjusted those tables but you might want to ask.
