Here is a quick run down

Last June I bought a trinity for my Charger SRT. when I tried to tune it it said I already have a tune on it and failed to load a tune. I was posting on the charger forum with MikeL about it he said I could call and you could force a marry to the car. Well I never called ...

Did you post this over in the Dodge forum? Might get more help.

OK, just checked...my upgrade is crap. I have a U7193 for my lifted 2005 Silverado. Put it back to stock and ran that predator on my 2003, worked like a charm. Tried to use my "Upgraded" predator in my 2005, did not work, "Unknown Error" again. Which is crappy because before the "upgrade" I could at ...

The "service brake booster" message went away. Called tech support cause the tool read "Illegal Programing" when I tried again. Made sure to unplug the fuses and such, still not working. Keep getting "Unknown Error". Im gonna try another Predator to see if the upgraded one is just crap.

OK, just got back my U7193 from Diablo. (had it upgraded). The tool lets me go through all the steps to modify tune, but when I go to install it, it gets to 4-5% then gives me an "unknown error ()" message. In the tool menu, it doesnt show anything for hardware or Bus, and shows the Bus as untested ...

Well, lucky me. I found out it is the Predator. A tech at the dealership had a new one for his 2005. He returned his truck to stock and hooked the diablo to mine. It worked, so Ill be sending in for a RMA to get the upgrade.

Any help for me? Was there any reason to supply my calibration ID's and engine size?

OK, will sending in my predator for updating solve the compatabiliy issues? I am having some work done Friday and will pick up the truck Wednesday. I will ask the dealership to flash the most current program. If the predator still wont communicate, then what?

Any more help on this?

Any other info needed?

I have the 5.3

So do the Calibration ID's need updating, or just the predator, or should I do both?

The Predator displayed 8 ID's. Just FYI, it is Bios 6.01, software 2.1, hardware 1.01.

The message Im getting is something like "Unsupported Vehicle" It pops up after I enter my transmission type. Should I take it to a dealer and have them do a flash update?

Quick question. I have an older U7193 that wont work with my 2003 Silverado. Will this upgrade allow it to work with my truck?
