Probably the high load tune for CP-e CAI and CS racepipe will work pretty good.

I can't be sure either without looking at some logs.

Well, the log is incredibly clean considering the huge potentially rod bending load spike at the beginning.
The tune is fine but you seem to have some boost control issues on your car. Do you have an aftermarket boost controller, or was any work done in that area which could potentially have ended with reversed EBCS lines?

P.S.: add MAF g/s, desired air fuel ratio, actual valve timing, ignition timing and vehicle speed to your log. You can remove barometric pressure.

im running the oem BCS but maybe the line from the BCS to the turbo inlet pipe is loose and i was not on a clean flat road maybe some bump diturb the log... But i will do another run somewhere else, do you think a should lower the load table in the low rpm to prevent rod bending?

That line being lose can only create lean conditions (and not even that serious, 8-10% maybe) and it will not prevent the EBCS from discharging/bleeding the excess of boost, whether if that happens back to the intake as it should or in the atmosphere.
However one of the other two lines: from the turbo compressor housing to the wastagate actuator or from the wastegate actuator to the EBCS can lead to some issues if the first line is damaged/lose/punctured and if the second line is blocked/kinked. Or if the EBCS lines are inverted.
It is very unusual to see such a big load spike on an OEM turbo even in this conditions, maybe the turbo is not OEM? Is it a hybrid or some BNR S1 or a Kinugawa/Mamba replacement turbo?

Are you running a tune you did yourself or it's the off-the-shelf tune?
I'd say for starters lowering the 2500-4500 values (or across the board) in the BCS DC Base table with 10% at least, or even 15%, and let the ECU compensate up if it will even be the case.

Nop its only the k04 2 years old and for the tune in BCS Table im just a little bit under the value from the OTS Stage 2 CPE CAI maybe if a send you the map it will be better

Well, you are pushing that little turbo quite a bit with this tune. Even so I can't see it realistically achieving a load of 2.6 with only like 50% WGDC, so there is some issue on the boost control side.
P.S.: in your tune the throttle reduction boost limits are higher than the fuel cut ones, you may want to correct that. Also setting the min AFR to 10.8 may not be the best idea especially on 91OCT, neither commanding 11.5x past 5000rpm at WOT.
