Damn, I'm not where I can access HPT, but there is a big difference in one of the boost table axis between the two base files, one tops out at 17.x psi, while the other is around 23. Raise that sucker to 25 or so in the last column axis. One of the boost controller tables, top scale axis. Damn... I forget too much ****.
Maybe you are getting so far out of range it's shutting it down.

I had two 91 octane files for him. He originally had the factory sensors when I first tuned him on the stock turbo then he upgraded to the 3 bar sensors. I accidentally sent him the factory sensor file which he did a write entire on the get rid of the trifecta underlay. I realized what happened and sent him the correct file but he needs to do a write entire with it to correct for the map sensor scaling and torque scaling. He already tried a write calibration and no change. I believe this is the whole issue. I hope that is all it is. Crosses fingers.

I've also had the MAF freq limp me out over ~12,000 hz. Bigger diameter MAF cross section would fix that.

I don't remember getting any codes when my MAF freq spiked and limped me, but that was last year. I forgetz. It was when the intake was sucking water & I saw 13k HZ spikes on occasion with a MAF relocate to the cold CP.
I found a post on HPT of the table I was talking about above, Proportional Max, Desired Boost axis.
If the 3 bar file doesn't do it, ramp that scaling up to what you see for boost.
I understand that first hand, and gave it up.

We will see this afternoon when I get home. I think its the intake collapse. The elbow on the CIA Sri seems weak. A collapse would cause a super rich condition for a split second. I did a write entire this morning with the 3 Bar file. We will see I guess. I don't mind trouble shooting, I like learning new things.
Also I am getting no codes

Theorethically I can run open turbo intake side since I have the maf relocate anyways. That will be a quick check for collapse.

I am gonna try the intake elbow when I get off work today. I was almost able to squeeze it shut with my hands where it connects at the turbo. The stock turbo was flowing 30lbs VE on the last setup. The new turbo hits that much more violently at a lower RPM. So step 1: Change the intake coupler. See where that gets me.

Also one thing I noticed about the BNR2871, the intake side where you connect the intake to is smaller than on the K04. This might be why I am getting collapse. It might be creating a "pinch" in the coupler.

ROTFLMFAO. I had the intake off my 99 Dakota RT back when I first started driving. I was putting JBA shorty headers on. The next morning I put the truck back together and drove it. The throttle stuck nearly wide open. I was like WTF is wrong. I took the intake off and looked at the throttle body and there was a big ass toad stuck in the throttle body. His legs and ass were hanging out. He was smashed up badly but still alive. I will never forget that day for the rest of my life.

You would think the intake would larger on the 2871 not smaller.
