340i BM3 Stage 1 31+ PSI??!
Need help understanding this. I'm new to bm3 and logging etc and have been testing different fuels/maps etc. Car is a stock 340i except for stage 1 tune and awe exhaust. I typically run the stage 1 multimap but wanted to log the dedicated 93 map to compare. Anyways, the targeted/actual boost levels seem alarming. Does this seem normal to you? I have read the stock turbo cannot handle this much boost. Also, the rpm log also seems wonky. It normally has a relatively linear slope, here its seems to accelerate at a faster rate higher in the rpms. Any input is appreciated.

It doesn't unless that's how you have it set.

All other map logs on multimap show 17ish psi so I don't think I have it selected. That said the math does sort of lineup? I'm at a basic level reading logs but nothing obvious seem stand out as being significantly off, you would think if it's running that much psi there would be obvious issues. The rpm curve is still a head scratcher.
