2005 300C with 13 5.7 VVT Motor, 392 cam and full exhuast advice

Hello all,
Looking for advice on what would be the best base tune to start with for my current setup. I have installed a 392 cam,mopar performance springs,srt headers and a full exhaust. It is running fine at idol on the stock tune but will not stay running after you give it 1/4 throttle or more. I have downloaded a stock tune from a 2011 300 SRT with the 6.4. Would this be a good starting point ? Current setup is 2013 5.7 VVT behind stock 05 NAG 1. Also this combo is running on a custom harness/ECU setup made by Chris at Hotwire auto which I logged 20k trouble free miles before I decided to do the cam swap.

Thanks for the advice. Getting this ride ready for power tour 2020.......

Hello,
My Tune, might help You a bit.
I have similar setump - 345 with 392 CAM, Short Headers, MDS, NAG1.Attachment 95423
SRT stock tune is not a good idea.

I'm subed for results, I have an 04 SLT ram that the owner wants to do something similar , but we are looking at a 363Ci Eagle with the SRT392 Cam....OrangeRT which intake did you use ?

retune your car .. every car have its own way to tune it for best and you cant use 392 tune in your 5.7 !
