I'll do it and I'll tell you if it worked. Thanks very much for your help.

After using the multimeter is seems the B41 (TC) is connected to the pad of the missing chip. The one missing on the green circle: https://prnt.sc/6MWUiIyI5DZ1

This is my NA ECU, but it is different from the one on the link you sent me. Seems like is missing a chip.

Do you think it will be able to "solder" to transform this NA to turbo version?

I think I've found the issue, my M4.4 ECU is from a NA version. From what I've read it seems like the M4.4 should be from a Turbo version Do you think that matters? It absolutely matters. The NA ECUs don't have the components populated on the board for the TCV control. Just two 0 Ohm 0805 resistor ...

Do you think that matters?

Another thing, is that my 855 is from Europe, probably the bin isn't the same. Does anyone have a base file for a European 855? Thanks very much!

can you send me your bin file in order to compare?

I've been changing the Target Load Setpoint and it doesn’t seem like it’s doing anything. Am I missing another map or limiter that could be capping the load? I’m not seeing any noticeable change in boost response after adjusting it. Any pointers on what else I should look at?

I need a xdf or a file that can raise the turbo boost. I've been trying with 608_rev5b.bin and Rev5b.xdf and It seems impossible. can you help me understanding which map raises the turbo boost? I've been trying the load target

Hello guys, does anyone have this file: 608_rev5b18PSINew.bin?

Thanks very much!
