2016 sierra throttle wont fully open (bolt-on)

[muhannad9889]

hello everyone,

am tuning a bolt on 2016 sierra. at the start of the run, TB will fully open..ish and then it will stay around 50% range. did try to raise driver demand tables so the predicted tq be more that actual but with no success. the old data log only with catback ,CAi and it was perfect. am nowhere to solve this and its my fist time seeing this since i do tune bolt on trucks. i do appreciate if someone can shed some light

tune with data long and log will be attached.

What was changed (mods and tune) between the old and newest logs? Your requested torque (driver demand) and 376 ft/lb but the engine torque is ~430 - maybe try upping the DD table. In the old log the Final Throttle Torque Req is greater than Engine Torque the whole time, but in the newest log the requested torque is less.

If you tried upping DD table, you may have to do some torque table tuning.
