A Few ?'s

[todd.scallions]

I received my Gryphon towards the end of January. I installed it and then set it to the canned tow package. I changed the gear ratio & tire size, but the truck seems to be shifting crazy and idling at a higher RPM. Shifting from 1st to second doesn't seem to happen until I'm close to 3,000 RPM's (barely giving it gas). I just went back to stock this morning and I could tell a big difference. Seems more responsive now. Does this sound right? Did I miss something? I just figured I'd leave it at stock until my custom tunes come in. Also, should I hook this up to the PC and update the firmware on it?

Also, I just decided to add high flow cats to my truck and I haven't received my custom tunes yet. Is there anyway to update my custom tune order to reflect these changes? Or does that even need to be changed for custom tunes?
