Was watching my boost psi in the data logs and I’m not even getting 6 psi I’m on stage 2 + MHD and I’m pretty sure I used to get up to 18.2 and I’m talking about max rpm’s full boost idk how I’m getting 6 any recommendations what I should double check. Could it be my wastegates one of them feel easy to push in while the other feels like it holds the pressure much better new turbos?

Sitting at -7.5 on idle. My numbers seem all off please give any advice

I went onto the v7.1 map like a week ago to try it out everyone saying it’s better and it kept giving me a 30FF and engine malfunction but when I switched back to V10 im not getting engine malfunction or 30FF it’s been in my shadow codes a couple times but not throwing it as active

Ok, Do you have any 3rd gear WOT logs?

I don’t know how to post the log I took one thought I think second gear WOT but I can go back out and do a 3rd gear one.

What to log? Most are already selected by default but here is a general list:

Boost
Boost Target
Coolant
Cyl1 Timing Cor
Cyl2 Timing Cor
Cyl3 Timing Cor
Cyl4 Timing Cor
Cyl5 Timing Cor
Cyl6 Timing Cor
Fuel Low Pressure Sensor
IAT
Lambda bank 1
Lambda bank 2
Load actual
Load req
Rail Pressure
RPM
Speed
STFT1
STFT2
Throttle Position
Timing Cyl. 1
WGDC After PID
WGDC Bank1
WGDC Base Value

Most likely you have a boost leak but check this out. https://bmwtuning.co/bmw-n54-30ff-en...-repair-guide/

It'll be similar anyway. As above you i'd say you have a nice boost leak.

Here is my 3rd WOT pull I forgot to turn the log off for a sec but you can see it at the beginning.

Fast work! Yeah i'd be visiting that link and going over vacuum lines connnections and Intercooler pipes, Charge pipe connection, Blow off valve etc.

With the vacuum lines usually around the oil filter housing is where the hoses perish.

Major boost leak or your waste gates/turbos could be shot. Could be boost solenoids too but I think more likely boost leak or worn turbo hardware. How many miles on the turbos?

195k they are the originals. They are well over due. I want to go single turbo might just have it sit until I get one
