Ok, so here's some screen shots and my current MSQ file. Any help from anyone would be great. Datalog will be coming soon.
Thank you.

i've always found I need at least 3% dashpot factor
you need to change dashpot decay to 1 from 10.
your PID isnt great; I think you should be more like P-50 I-25 D-40 to 60
you PID delay and ramp times are long, this makes the idle speed hover high for a while...
if you want richer AFRs at idle, increase the values in your IDLE VE TABLE.

This is for the MSM. Which now has a 2560r turbo. Thank you for the advice. I will try and get to the car this weekend and try those setting. Heres a screen shot of the changes, does this look better?

Just a quick update.
I used the settings listed above without success. I ended up doing a vac test using some brake cleaner around possible leak areas. I found that I have a small vac leak around 2 of the new injectors. So I'll have to take them all out and reseat them. I checked them good when installing to try and prevent this, but ??? I did notice that the FIC injectors are a bit longer than the 305cc units I had in there.
I'll update again once the injectors have been reseated
