Dodge challenger SRT8 2008 SMS supercharged 3000-3500 rpm limit issue

[R3nciukas]

Hello Guys. I hope I can get help in here.
Mods: 20mm smaller SMS supercharger pulley(0.8 bar or 11.5 PSI)
New walbro 450 lph fuel pump
New forged pistons, connecting rods
Engine completely rebuilt.
No catalytic converters.

Story is that, everything is almost finished with mapping on hptuners, BUT now we have issue, doing dyno on 3rd gear, pressing pedal to the bottom and when it reaches about 600NM in 3 - 3.5 k range, it starts limiting the power, its clearly visible on dyno results, sound like fuel is being cut off. We tried almost all setting in trans and engine about torque limiter, looks like nothing is working. Ofcourse I can bypass that rpm issue on that range, but not pressing pedal fully, so logically something is limited for some reason. any ideas ?
waiting for answers

Are you still having the issue?
If yes, share the log and tune. Which transmission does it has?
