when you go in to the diagnostics screen on the pred it comes up dtc codes. then specific codes, then there is a third option to go in to. normally i just read the codes in the first choice on the screen, but my question is what is the third option on the screen for. i see codes in there but do they mean anything:confused:

I looked at those a long long time ago. I think they might be freeze frame codes but I'm only guessing. Mine had a ton of them since it had never been hooked up to a TechII since it rolled off the assembly line when I read them.

I installed the 65hp tune, Now If I want to install the 85hp do I simply modify to the 85hp and be none with it?
