• I see no where you've asked for a pcm code for the 02 f350 auto so does it not matter

  PCM code will determine the chip you require

• I have the 8 position switch already on my truck but the knob is missing it’s really hard to change postions on it is there a way to get replacement knob

  Contact Quadzilla direct.

• I bought this chip a while back and up until recently was great sometimes i have to shut the truck off and turn back on. I know the chip doesnt work when my truck doesnt go to high idle when set to high idle setting and notice no power gain. Double checked to see if chip was unseated and appears to be ok. Any ideas would be helpful?

  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.

• What is the Whisper Mode on this chip?

  Truman Lowrance | 10/14/2020

  The whisper mode is designed for drive- thru’s , banks etc. so you do not have to shut the truck off.

• Hey man what’s going on, I have a question before I purchase. I have a 1997 Ford F-250 7.3. What should I upgrade first before installing this chip so I don’t blow my truck up. Any recommendations? Let me know. Thank you

  Edward | 6/18/2020

  No upgrades required. We recommend having a cold air intake and performance exhaust.
