basically yes but better to modify more axis values to scale map properly

If I understood correctly;
Since I am increasing the last row by 200, the rest should be scaled by the same %.
I cant really log my tests. I do have Vida and Dice but its slowwwww.

you can make last axis values for example 800 and 1000 mBar

The right way to do things successfully is IDA.

look at the 3d view and make it smooth, you can paste the values from the last column down 1 and then create your 1000 to suit.

Not sure I understand what you want to do. Do you want to control at what RPM you start building boost?

Yes, the limited amount of knowledge i have on ME7 made me think this way but now I dont think its right? I looked at an bin for a S4.
I want boost to build around approx 2500 rpm.
Peak 14psi at 5500rpm. I can post my LDRXN.

No you should do that in LDRXN and not KFLDIMX.

That was how I understood as well from all the reading. I will experiment more with ldrxn. Its just that not having a obd flashing capability that does not cost an arm and a leg make this so much more time consuming. But whatever. If I post my bin can you tell me if KFLDHBN will need to be increased as well?

Wouldn't that create the biggest overboost spike ever?

mine has 110 in 2 cells from factory. It will show what the turbo and actuator actually want to make and if it gets pulled back by other maps. Although I can't remember what he was actually going for now I was wondering if he actually changes things on the car before asking the next question.

Right now everything is stock exept for injectors. They are from a T5.
I modified hpa axis in IMX to 1000 on the last colomn, and the 2 before that respectfully. Kept the map data the same. Took the car for a drive and after 2 days boost builds to 14 psi and tapers off to 10psi towards 6000rpm.
LDRXN has been modified as well. I will post it later. I did not stay in WOT too long since I did not have Vida with me to log. That will be done this week.

That sounds like progress, are you happy you know what you're doing now?

If that is supposed to be sarcasm, remember that things written in forums are not always read the same way by 2 different individuals.
To answer your question, no I am not happy yet. I don`t have the knowledge that most of you do with ME7 since this is an older ecu. I am doing this for myself and finding time to work on my car is quite hard.
I appreciate the help so far.

Not sarcasm, I've taken an interest and you do seem to be getting somewhere. What's next then? Have you compared the other maps in T5 cars? KFZWOP and KFZW are detuned if ur starting on an LPT, then maybe revisit PED IOP and IRL to get the power delivery you want if your boost limits are now high enough.
