Working on a Hellcat with a Magnuson 2650
Previously had a modified stock blower and drove around with a vacuum leak for about a year, (a few hundred miles, vehicle is rarely driven). So while it was apart the owner wanted to switch blowers.

Just started tuning the new setup and have two issues:
1. The vehicle wants to run severely negative timing (-64 degrees) on cold start so I set the minimum timing in the spark section to -5 degrees on cold start to try and remedy this. Is there a better fix for this?
2. The idle hangs up around 3000rpm after any hard acceleration. I'm not sure what to modify to remedy this.
The cal file and a log are attached.
If anyone has any ideas or has ran into this before let me know!
Thanks!
