Why on earth did you buy a tuned ECU?

It was tuned using tuner pro so I figured I could compare the two.

You need to forget about any of that and figure out why your turbo is limping at 95% DC. Your car has serious mechanical issues, and you're buying random ECUs??? Studying other people's tunes is going to get you no closer to understanding how any of this works. You don't even have any idea if *that* tuner knows what they are doing. |

Yeah your right.... Let me go back to the original task at hand. Boost is not where it should be. So in the wiki I read PID and there is a couple things that could be the issue, KFLDIMX and positive deviation.
Being that these are software related we can rule them out correct?
Hardware wise the other things I should check for is the WG , N75 valve, and any boost leaks.
Am I on the right track?

Correct. Start there. You can also disconnect the WG line entirely to see if the car will make boost (carefully). But before doing so, make sure you understand what disconnecting the WG line does. |

Here are a couple logs. One with the N75 valve disconnected from wire harness. The other is with the Waste gate disconnected from the N75 valve.
ECU identified with following data:
HWNumber = 0261206890 (requested was 0261206890)
SWNumber = 1037363351 (requested was 1037363351)
PartNumber = 06A906032DL (requested was 06A906032DL)
SWVersion = 0004 (requested was 0004)
EngineId = 1.8L R4/5VT (requested was 1.8L R4/5VT)
VAGHWNumber =
ModelId = G

What is problem with you car? I can't find in tread?
As I can see , your turbo and WG are okay. But that desired boost is impossible high for K03S, it will never achieve that. Also what happend with fuel, your lambda go bellow 0.75

The original issue is fixed. Now the issue was not achieving requested boost. Attached is the graph we went off. As for the fueling this is the first time it’s dropped that low.  Sent from my iPhone using Tapatalk |

1. Don't use taptalk, it is bigger shit than req boost in that file 2. KO3s Can't make 20 psi at 6000 rpm, buy GT28 if you want that |

Sorry, my mistake I was confusing this with a different thread.
Yes, drastically pull back your req boost.

Here is what the fueling looks like in Tuner Pro and Ive attached a log with every thing connected.
Ill pull requested boost back. As far a the fueling issue I looked over my stock logs and it seems to follow the same pattern. I have 4bar regulator, stock injectors and just replaced my O2 sensor.

One thing at a time. Get boost where you want it first.

I dont get what you are doing here. You see what your turbo can do. Why did you just reduce the whole thing instead of leaving the low end where it was, and tapering up top?
What is was your rationale?
