It could be a faulty Mac solenoid. You can find it here:

Hello, Burger Team
I think i found reason but dont know how solve it.
when turbo is pooling wgdc sets at 33 and boost rises continuously, but after 15 psi wgdc sets 0 and boost goes down to spring pressure and cant reach target. for reference i attach logs map1 and map2

v13_5 firmware

Added anti-bog logic selectable with FUD.4 and pulling clutch wire. Details here: http://www.n54tech.com/forums/showthread.php?t=52657

T1) Adjusted boost safety system so that boost safety for map1 (WG spring) change over is 3psi over map target OR 1psi before sensor runs out of range. Whichever is lower. The user adjustment boost safety setting is now used only for in dash boost gauge calibration.
T1) Fixed another bug in the 2STEP logic. Seemed to be working much better on our development car. Let me know!

What exactly entails the in dash boost gauge calibration? scaling it to your own max psi range? or just generic calibration for your model car? Thanks

Same as it has always been. Gauge reads from 0psi at empty to user defined boost safety at full.

I was always curious how it was scaled from the perspective on a 3.5 or 4 bar sensor. Thanks Terry

Which turbo manifold are you using? You take forever to build any type of boost. What size of turbo? Just curious man

Yeah you should order the MAC solenoid from BMS. I've had mine since 2015.

This log is much better, everything is finally working.

Okay, now do the following:

Set DWP to 70
Set Duty Bias to 50 Across all RPM
Set FF to 50

After you saved all those values, go and do another log. Try and make your own thread please so we don't clutter this up. I will have to start deleting your posts soon.

Make your thread and post the log here:

You'd need to setup map 6 for that.

I'm not really understanding what you're asking. For a single turbo you will need to update the Jb4 to the single turbo firmware. Make sure you have single turbo MHD flash loaded as well.

Jb4 firmware is on the first post of this page:

You're a wild man.

I can't believe that you're still running twin turbo firmware on your ST set up.

Lets take this back to email and I can tell you what settings to run.

Can you get me a log on map 7 where you have both PI and Meth working.

I deduced that he's attempting to communicate to you that he's concerned with this AFRs differing from bank to bank. I would hazard a guess that the oxygen sensor on bank 1 requires replacement. But would be best to at least run the correct firmware! Lolz

Sounds like they didn't plumb the waste gate lines properly. A simple oversight usually.

these are the codes in the DME
002D33 ABSOLUTE PRESSURE SENSOR
003100 BOOST PRESSURE CONTROL

im going up with my trailer tomorrow to get the car and look it over myself if anyone has ideas with these codes it would be extremely helpful.

Those are all boost related codes. Check that they plugged in your TMAP sensor on the charger pipe and that its connected. Check the plumbing to your waste gate lines are proper. Also make sure that your MAC solenoid is actually plugged into the connector. I guess also check the silicone charge couplers attached to the intercooler. Did you upload the proper firmware and are you using JB4 with an MHD bef?
