Hello, I'm facing little problem with requested load. I can't request more than 143 load / 1670 boost pressure at 6100RPM to revlimit. I tried some things, but it still stays at this value. I'd like to reach 1800-1750mbar boost at redline. Engine stock BWA 200hp with 3" downpipe. How it looks: KFLDHBN  KFMIOPS:  KFMIOP:  KFMIRL:  KLMIMAX:  LDRXN:  How can I get more load than 145 at 6000RPM+? Maybe there is something that I don't understand, maybe there is something that I missed. Same thing is at 4000RPM, I request 170 load, what I get at logging car is 160% load. Maybe I'm stupid, but maybe someone will explain me something useful  Regards! |

I have never exceeded 880C, this value was always at redline. Max -3KW for a while at 1 cyl. Lambda keeps to be 0.77 like i request. There is no intervention via lambda control, it stays at ~5% max, fuel high and low pressure is ok. I've been thinking about that I didn't changed additional map that is needed. |

Desired boost 1650@6000rpm slighty drops to 1530@6800rpm, wastegate 51.5%@6000 increasing to 53%@6800. I even tried to do things something like this with KFLDIMX and KFLDRL:  Should I play with KFLDRQ0-2 ? |

I have logged IAT I was been thinking the same, when it had to be 25C outside (now it's cloder, like 10C) I had max 40C at redline. Injectors timing never passed 8.5 ms, those values aren't from this version of tune, but it had almost same results like this modify. Also I know I'm near turbo limit, but my boost tapers to 10psi, I heard typical stage 1 tapers to 12-14psi. WGDC at 50% is weird for me also, because I set it really high, maybe should it be corrected in KFLDRQ2 also? Here is my newest log: |

Finally I have pass thru this limit. Belive me or not, but LDRXN was the problem  Now I'm at turbo efficency limit, it can't boost more Here are logs, I did them after change values at LDRXN. If you see something wrong, or have any tips to do something much better just let me know please BTW. I tried to do the best logs as I could, almost everywhere 4th gear, but you know, I did it on public road, it's sometimes hard. I also cut them for be more clarify. |

Yes I know, the issue that I didn't go above 1670mbar was too low LDRXN value, I have set it higher and now it's ok, I just put logs of this change. |
