PCM code will determine the chip you require
Contact Quadzilla direct.
I would go back through the install process. Making sure the chip is seated properly etc. if this does not help.
The chip may need to go back to Quadzilla to be reburned.
The whisper mode is designed for drive- thru’s , banks etc. so you do not have to shut the truck off.
No upgrades required. We recommend having a cold air intake and performance exhaust.
