    So your intake starts at 94.5? This tuning school book makes you think you have to change the values for the IN/EX mins and maxs. I ask because this book says that both sides have to equal 228.5...

    Here is my intake table. On my 2015, the stock tune totals 241.

    I realize you need to be convinced in a lot of different ways and from many people about how the entire system works, but I have stopped trying to help as I have clearly told you exactly what to change, what you don't have to change, and you continue to further research and question. The Tuning School is a great book, but often gives recommendations on making changes without any real reason to do so and in fact recommends changing things that the writer of the book wasn't sure if it was required but "better safe than sorry" and recommended changing them, I described this to you as being "a cleaner tune." If you had a better understanding of how the VVT system works, you wouldn't be wondering so much about all the settings and looking for multiple affirmations from multiple people and have already fixed the issue with the car.

    Hemitoona, myself, and few others have written out quite helpful responses to other folk's VVT questions in their threads, use google and/or search on this Dodge forum and you will find them.

    FWIW - 5.7L engines total up to 228.5, 392's add up to 241. If you read carefully in your book, you would see they are tuning a 5.7L truck.

    Have a log from before? Can overlay the aircharge, see if its taking in more air, i.e. making more power. Post the tune you uploaded.

    Followed your cam table exactly, that's good, problem is now you have almost no timing. Go to Spark->Advance and find the WOT Base table, copy the table, then open the WOT VVT Lockpin table, and paste in the values.

    Lets get a fresh log with the added timing, then see the airflow again. Might want to retard the cam just a touch earlier, but i want a new log before that to check for any knock etc.

    Also, open the Airflow->Electronic Throttle-> Maximum Demanded Throttle Voltage, set the entire table to be 3.7998 (bottom value).

    YOu need to take a full read with the a8 transmission controller, there's nothing scanned in your tune read out, lots of torque limits in there that are keeping the throttle at 50% through 1st gear.
