So I can't seem to get my WOT and high rpm tune to behave.. I feel like I have little boost in the high rpm (above 4000), I logged tonight the best I could with the annoying san diego traffic even at 9:00 at night.. I don't think I was able to satisfy the filters needs but I tried doing some 1st, 2nd, 3rd pulls. I'm new at the whole ecu-x thing so I'm not having a good time putting the graphs together.. Map and logs attached.

Those logs are totally worthless.
Get a 3rd gear pull wot from 2500rpm to redline

Honestly the car isn't making much boost up top so the thing takes forever to run out 3rd gear.. I will give it a try again today, but the traffic around here blows for it.

Then forget about running it out. How about staying WOT in third starting at 2500 rpm for longer than 1 second  And please try to only have the logger running when you are actually doing something worth logging... In any case, your WGDC is at 10%, which means you are in limp mode. Any codes? |

Okay did some more runs, with hold WOT in 3rd from 2500 to close to redline twice. I will go pull the codes now but no check engine light..

I'm getting error code P1557... deviation code obviously because my turbos aren't making over 10 psi! lol what the hell is going on.

You are requesting too much boost too soon.
Why are you requesting max boost below 2700 rpm?
Your WGDC is stuck at 10% because it threw a code when your actual can't meet requested ON BOOST RAMP.
Clear the code, and do one pull in 3rd.

I'm using the rs4 ldrxn as a baseline so I figured my turbos should be able to make close to what the regular bosch k04s are making? So should I adjust the boost curve to build more gradually and then log again?

Hmm. I can't tell if your LDRXN is ok.
I'd need to see a log of your car with the DTC cleared to see why it is being set.
If you LDRXN is RS4, and you aren't requesting more than 170 load at 2700rpm, you might be ok.

Yeah well the map i'm using it up top, but any how I adjusted the ldrxn to be less aggressive and now i'll go run again. My wastegates crack at 10 psi, is there a possibility that it's the n75 valve control causing the issues?

Impossible to know w/o seeing a log if what is happening when your ECU throws the code...

Also both times i've logged, about 10 minutes into the session the car jerks like complete loss of everything and ecm light flashes on rpm gauge, this is only when logging, when this happens the logger throws error code 8... again only happens when im logging and it happened both times and cruising speeds on highway.

Okay I cleared the codes twice and ran two logs with two 3rd gear wot runs. Went into limp mode both times I believe. Logs attached as well as revised map.

you're triggering the DTC long before I see it in a 3rd gear pull... so all 3rd gear pulls have 10% dc
STAY OUT OF BOOST until you can start your pull...
I dont know why you are requesting so much load/boost at such low accel ped positions.
