Help Needed Can't find these DTC's
I went to change the Hypertech tuning level on my 2004 6.0L today, and it reported 3 codes: P0404 P1335 U0306 I found the first one, can't find the others. Anyone got a good online lookup site, or know what these are?- LCW

Can't shift out of park?
2004 F-350 6.0 Auto dually About 50% of the time I try to shift out of park, it won't release whatever lockout is in effect. I then have to go through a random number of cycles of letting off the brake, pressing the brake, try again, etc. Eventually the lockout releases, but I haven't found...- LCW

Hypertech Max Energy or E-Con?
Anyone running these in a 6.0? The performance increase would be nice, but my main interest is in the fuel mileage increase. 13mpg in town just sucks. How much of an increase are you seeing?- LCW

Engine runs weird sometimes
Hi all, I just bought a used '04 superduty a week ago, and I've noticed an intermittent issue that doesn't sound so good. Most of the time it runs just fine, but every now and then, I'll have this problem with an off-idle stumble, then once I get up to a steady 45-50mph, the engine seems to...- LCW
