I would also love to know an "expected" date on the release of the Trinity monitor and if it will actually be a stand alone gauge system like the Quadzilla Commander or if it will be just a tuner/monitor combo. If it will be a while before it's released, I guess I'm gonna have to go with the ...

Well revision 7 still has the "surging" issues. You need the new test revision that Johan has realeased. Email him and he will get it for you.

Dodgezilla.... that sounds like a different problem to me. The "surging" or "shuddering" that I was experiencing lasted for about a second and the truck ...

Drove 270 yesterday and no surging with me either. Good deal....

You need to return the truck back to stock settings before updating your Predator. To determine your Cal ID# just plug the Predator up in your truck and go to the Diagnostics menu I believe. It will give you an option to find your Cal ID#. Just scroll through the menus; you will see it in there.

Me too!

Revision 07 seems to be issue free on my end. When you buy the Predator it should already have revision 07 in it....

Johan.... I have been driving around for about a day now with mixed highway/city and have yet to have the truck surge on me. I reloaded revision 7, so it must have something to do with one of the new features in revision 12. I'm guessing the tune on the fly is the culprit.

I went back to revision 7 and have not had any "shudders" at all. The glitch in revisions 12 and 14 is definately the tune on the fly feature. I hear you on that though Dodgezilla.... the tune on the fly is definately nice as well as the tire size feature for us guys with larger than factory tires ...

Thanks MegaBOMB.... I may have to try that to see if it works. That would be great....

Johan..... If it's gonna be a few days before you get this figured out, would it be possible to re-release the revision 07 for the U7131? I know the truck will have a rough idle to it, but that can be fixed by not running the AC while idleing. I'm about to go on another trip and would love to hook ...

The factory computers are way off from the beginning. Best way to figure out your mileage is to hand calculate it. Sometimes my overhead will read 26-27 mpg but I'm actually only getting 17-18 mpg.

Haha. Yeah I definately agree there. I'm sure they will have a tune finished before long. I have talked to a guy by the name of Gary in tech support and I know that Johan is working on this thing constantly. He's doing his best and hopefully there will be something within the next few days. At least ...

If yall are saying that the trucks did not do this before the revision 12 update, a new revision that is the same as revision 7 with the rough-idle/idle-up/tire size adjustment would be perfect. Maybe Johan can help us out here. I took off the Predator and I am just running the Puck as of now. I ...

Let me know what to do Johan. I think I can help you out.

Johan.... the truck shudders with the Predator/Puck combo or just the Predator. It's not as bad as before (like I said) but it still cuts out often. I have also thought about what "hasman70" says. That sounds like a valid point.

My Calibration ID is 35325553AQ. Same as "tim r73703".
