2016 F30 340 not hitting boost target

Hello all, I have a 2016 340 with Bm3 stage 2 plus 93 octane. I have recently put the tune on this car and it felt a little slow on the top end. After doing some logs my wgdc is 100% when below 4500 then drops to 89% around 16 psi boost. Boost target stays at 20.7 the whole time. So I’m not sure if the tune is telling it not to build boost for some reason. Car isn’t pulling crazy timing or anything. Here is some logs, Thanks

Seems like your hitting torque limit. DME wants to send 20 psi to the turbo and communicates with the TCU.

TCU says 'hell no' and takes 14-18 psi.

(just my guess, I'm not an expert.)

ZF8 TORQUE LIMIT

Here's a video that might describe what I'm trying to say more accurately than me.

Hrm interesting. I’ll take a look into it. I figured since I had dsc off there would be no limiters. It also has stage 3 xHP trans tune. Thank you

Didn't know you had XHP.. forget what I said then.

Not sure what is happening there.
