Tuning help needed

Still in the process of making a functional tune for my heavily modded 14 SRT. Forged stroker 426 with single 76mm turbo. Tuning issue for it is a large stutter or cutout right around the vacuum/boost transition. Feels like fuel getting cut at this point. Anyone else with a similar boosted build on a stroker in 14 srt with similar experience and/or suggestions?

Appreciate the response, but we figured out the issue a few days ago. Seems the factory setting in the PE page for WOT fueling slope was too high. We set it lower and the problem disappeared. New problem though, when its running, the 76mm turbo is now too small to provide enough boost for the 104 octane tune. Have to replace it with 88mm turbo next week :/
