Infiniti Q50 tuning help

Hi,

So its the first time i do a tune for infiniti's thankfully this guy is my friend.
I am trying to make the car rev limit hard like what we usually do on LS & any other platform. I tried several things including torque demand on that specific map with no use. Whatever I do the car still holds rpm at 5,000 (soft limit)

Another thing that I am not figuring out is how to make the car make more boost. Tuning the platform is confusing unlike GM, Ford, Dodge or even VAG!!

Attached two files different tunes as trials to make the car rev limit hard & make more boost.

Any input is appreciated.

Anyone!!??
It's a Mercedes ECU so i guess there are guys out there who can help out.

post the stock file

How can you give more boost to these q50? I can't understand his way of working either

Anyone have any answers to boost control on these? Raising the desired pressures and limits that are currently available will raise it some, but getting them to hold a higher commanded boost to redline not happening. A limit table missing maybe?

Anyone have a stock Red Sport read?
