Good day all,

After more than a year of trying to understand this I have finally got to a point where the car is going very well.
I still have one problem though, on the top end I can feel that it is pulling back and there is a lack of torque.  I have logged the car and find that rlsol is hitting rlmxs limit.
Can someone please point me in the right direction to resolve this.
Car is an Opel astra mk5 OPC, 2.0 with GT28 turbo and forged internals.

Logs attached and TIA

Thanks for the advice. Let me see if I can sort out the above

You need wideband and see what your mixture is doing, it's not tuned correctly. Not on request and not on result for sure.
Also from the log (MAF voltage) it seems like you have massive turbo surge on spool. So probably turbo has wrong hotside for application.

The ECU is not doing anything here (in relation to pre-boost behaviour), it's purely your hardware.
So you need to leave the ECU alone and fix that first.

P.S. Screenshot is from torque monitoring map, which does not need changing, not KFDMDARO, and regardless you don't have any ARMD intervention.

Well just have a look at your MAF signal - there is massive pulsation in intake on spoolup.
You need to figure out what is causing that, usually it's turbo surge so hotside a/r might be too small for engine.

I don't remember if these have VVT, if they do try to remove the overlap and see if it stops surging then (spool will be later of course). If it doesn't have VVT and you have non-stock cams, make sure they're not timed so that you have a lot of overlap all the time.
If it does not change anything probably problem is elsewhere, e.g. bypass valve rapidly opening and closing or some other shenanigans.

You need to find the hardware issue. While your tune is really bad fueling wise (but it's bad in the safe direction, it's not unsafe), it's really not the reason for your problems here at all. So spending time looking at the tune will not accomplish anything.
The tune can stay exactly as it is while you fish for the hardware problem.
