Help 7.3 missing, no codes, did buzz and contribution tests

[Probuilder]

No the truck has never acted up without the chip, until now.
- It sounds like isolated cylinder miss. When running the Buzz Test, did you hear any cylinders that sounded different? Meaning... did any injectors sound "dull" or "softer" than others? When I had an injector issue with our truck, I was able to isolate which injector was the issue by doing a buzz test and listening for an injector that didn't sound the same as the rest.

The buzz test sounds equal on all cylinders, but the contribution test showed that the #3 & #8 cylinder showed about 80%???????? Not sure what that means, but that is what the Ford Stealers said. But, I am not sure as I didn't hear it myself, and the Dealer may just be trying to sell me a new truck.


Ford garage came up with no codes present, except the one that tells them it had a tuner in it, so they told me.
- Ford equipment doesn't tell them you have "tuner" on it. That's garbage. As for codes, driveability issues rarely set codes and you'll really need to be able to log PIDS such as ICP, IPR %, PWM, EOT, and maybe a few others in order to come to a conclusion as to which direction to look.
Will the AE Software scanner do these tests?

13: How much do I have to spend on an AutoEnginuity software to diagnos these problems with the 7.3 motor/ truck. I already have a laptop computer.
- Corey can help you with pricing on A/E.
That would be great, I found the Ford kit on Sinister Diesel for $379.95 is that a good deal.

Thanks for all the help, Troy You can call me at 319-432-4648
- I'm tied up at the moment but will be happy to give you a shout this afternoon when I'm back on the road.
A phone call would be greatly appreciated. Even though it sounds like it isn't a problem with your chip or program. Your customer service is above and beyond what I expected!!!!!
