2018 Hellcat Pulley Tune - Help!

Hello,
I'm trying to get a hellcat dialed in on the dyno, and keep running into issues. It is falling on its face/limiting? at around 3500RPM+. On the dyno graph, it climbs very cleanly to 550ish tq in 4th gear, and can't manage to get above that.
I don't know if it is a torque management thing, or with the higher boost pressures if I'm missing something? Any help on this would be greatly appreciated.Attachment 145284Attachment 145285

we tuned a bunch on 2.85 - if you want a proven paid service hit me up

The limiting factor seems to be torque, at about 680wtq it stumbles and falls on its face. Fuell pressure good, AFR's good, timing only pulling a couple degrees, 15-16psi boost. Pulls clean up to 680tq(which it gets to in a hurry) but then it won't gain above that and is a bit choppy cutting out.

Open your file and compare it to this one and then try making minor changes to your file based on this one. if i can help in any way your welcome to reach out to me. i dont mind helping as best as i can .
