Tohi2care, I gotta ask.....has your issue been resolved? OR are you just "tohi2care" :smiley_roll1:

Well at least I'm not the only one having this issue. Mine only happens on the tow tune. So far I haven't had a problem with the Transmission only tune. I tried 93 performance tune for a couple of weeks and didn't have a problem with that either, although I was concerned about the higher operating temps accross the board but have since learned they were still within normal operating range. I think eventually there will be enough notice by people experiencing this issue that our problem will be evaluated and fixed. I wonder if everyone's HEX Code has a similiarity that would narrow down the problem? I have accepted the problem of the rough running since its not a frequent issue and just don't push it hard when it occurrs. just pull over, turn off the engine and then starting it back up usually remidies the problem until next event. I have never experienced the issue while on the highway driving freeway speeds it is usually below 40MPH in the city. Although there is this little issue, I am still happy with my Gryphon. :fyi:

I thought I was alone with this issue, until I found this thread today. I've had this same problem for about a month now it's happened four times. The last time was today pulling up to a red light, the truck starts shaking and spudder like it's running out of gas. Hitting the gas peddle doesn't help, turn the truck off and restart and all is fine. So far this has only happened with my custom performance tune. If I use my stock tune the truck runs great. I also have a custom tow tune but only use it when pulling my boat and have had no problems with it yet. I hope we can figure this out, I love my Gryphon. 06 Lariat 5.4 43,000.

I contacted PHP and was told to put in a service ticket for the issue, which can be found under the support link on the main page. I've been out of town ever since so I haven't had time to do it. Will do it soon though; just got back.

Oh...ironically, I also have a 2006 Lariat 5.4 w/ 43k

Or you guys have the same truck but completely split personalities.

:hmmm:

My service ticket is in :thumbs up yellow:

For those of you having this problem, I highly recommend submitting a service ticket in order to assist PHP with tracking issues and general recordkeeping. I would NOT depend on this forum alone as a resource for technical support. We should be exercising due diligence in following the right procedures. Good luck to you all. :cheesy smile:

And just how do you find the support link address?

It's in my Sig...

Just sent in a ticket.

I got a gryphon in early sept and have the EXACT same issue. i thought it was coincidence, but it only does it on SETTING 2 / 87 economy tow. Drivability is crap. I had to turn it to setting 1 'tow only' or 'shift only' or whatever its called.

at this point it looks like this is a known issue with the canned #2 tune, not a couple coincidences. Good thing I found this, I was just about to start throwing parts like coilpacks at it to solve the issue.

I guess its time for a ticket for me then. btw...2006 fx4. is it just me or is this a lot of 06 models?
