I have a question about my 08 5.4L supercrew. I have a Gryphon with custom tunes and a afe CAI along with a 3" magnaflow SOS. I recently was driving and stopped at a light and when i pulled away at the green the truck had a power loss and sounded like a quiet diesel. I pulled over and shut it down and when i started it up it went away. This has happened twice now but a month apart. any ideas or answers? please help
Thanks
