Should I find out for everyone?Interesting but means nothing about the durability(longevity) of the engine at 9k
Even piggybacks are traceable. AMG in the Private Lounge stated they can tell whether a piggyback was installed, and Renntech noted this as well. There is no such thing as an undetectable tune on newer cars unfortunately. Even with a piggyback, the ECU is able to retain many "max" and "min" values for things like AFR, boost, timing, etc. and although a piggyback will not increase the "flash count" on the ECU, it will know and record the edited values that are not within the OEM specs.
If people are flashing Odometers on cars they can flash out any trace of a tune.
I have no experience with the piggy backs I just was told they didn't but that was a while back. I fully tuned my F250 but knew what I was getting into when I did it. The difference there though is that it's been done time and time again and it's actually better for the motor to ditch all that EPA crap they put on them. And the sad thing is that they KNOW that crap does more harm than good to the motors
addle: If the Voodoo was a tried and true motor than I would consider it but I just couldn't bring myself to give Ford any chance to deny a failed motor claim in the future possibly 
Correct.
Cause 9000 sounds cool!!! Presumably you'd need cams or a tune to take advantage of it.
You probably need more than that like valve springs and better balanced crank.
I thought I read a while back that roush had a voodoo turning over 10k.
Yeah i am curious what the stock limitations are. Usually raising 800 rpm would either be in with in the limits of the stock engine or you might need some beefier valve springs.
I have and can only set the shift point to 8200 max. Does the tune allow you to set it higher? I personally would have the tuner set the fuel cutoff back to 8250 to be safe.
