Need help with power cut at 5000 and 5500RPM

I'm in need of some assistance, I recently started the Pro-Tune process. I went out a few days ago and every time I would try to datalog in 3rd or 4th gear it would cut all power at 5000 RPM.
I went out again today and tried again, Traction control off and 3rd and 4th gear. It happened again at both 5000RPM and 5500RPM. At half throttle with boost it acts fine. I was reading another thread on Mazdaspeeds.org and someone said the clutch switch needed replaced, however the car starts fine every time. Just looking for help and ideas, I've included two datalogs, one from 3rd gear, one from 4th gear.

Mod list is as follows
-Kinugawa TD05-H18G
-Mishimoto FMIC with HKS SSQV BOV
-Autotech HPFP internals
-Grimmspeed ECBC
-Catless DP to full 3.5 Inch exhaust
-Damond motorsports EGR delete
-Corksport 3.5 Bar MAP sensor
-NGK LTR7IX-11 Gapped to .026
-Turbo inlet pipe with K&N intake

Thank you!

Good chance it's the turbo. Post logs.

 

I posted two logs in first posting, Heres the others

 

When I say power cut, I mean its like hitting redline. if I let it come down on RPM and try again it does the same thing. Almost like hitting a wall lol.

 

have you confirmed with your tuner that they diddnt set a limit?

 

I emailed 3 days ago and followed up this morning. Havent heard anything yet. I sent him the two logs from first post. Hoping it's something simple but since I haven't received anything yet I'm stressing. I've compared the logs and nothing really sticks out to me as weird. Long term and short term fuel trends seem to be good until it hits that RPM Mark.
Idk. I'll wait for a response to see. Just was trying to get ideas.

 

Tuner got back with me, doesn't think its on his end.
After looking through the datalogs I took the other night, every time I hit about 4700-5000 RPM spark advance jumps Way up. From about 5 to 20-50. I'm just not sure what to do at this point. Went ahead and got a new clutch switch from Mazda and did SWAS delete. I also tested my PRV and its bad so maybe that's the issue. We will see.
