You should be able to tune it without issues as long as they didn't put a password/lock on it. Have you pulled the file from the car yet? Only other issue I could see is if whatever software they used had parameters adjusted that HPT hasn't defined yet so you wouldn't be able to see them. I wouldn't think you'd have to worry about that and HPT support has always been good on adding missing parameters when requested via support.

As far as tuning the torque tables... Good luck lol. At least for me anyways haha. I'm working on spreadsheet to hopefully remeidy my problems but waiting on a few questions to be answered first so I don't just put together a sheet that will lead to more problems.

Do you know what year the motor is that was installed? I'm not sure on the 4.6 but I know the 5.4 had a lot of changes from the 08 to 9-10 years. Enough that I would think the pcm would be very unhappy.

Sorry that I wasn't able to help you more.
