from Stock to Tephra V7 and no Power anymore
So Today i tried the new map i made with the help of "Biggy VIII" 
and "ReaperX"
But somethings works not right. With my old map i had 435 HP and 590 Nm torque. Now with the new tephra map i got not more then 330 HP and 420 Nm torque. I thought that something with my boost values are not right. But i found nothing. Maybe somebody of you can see some wrong values. Please help

Well here is what you need to do next.
1. You can send your maps to Jay for a look, he has a lot of experience obviously. I'd also be willing to look them over.
2. Do you have any logs you could post or send from the before and after?
3. Have you done a boost leak test recently?

The reason why you have lost so much power may be significantly lower boost. What boost do you see on your boost gauge?
The reason of lower boost may be that you have enabled function "Drop Boost on high knock" in Tephra mod options, and your car is knocking. Therefore ECU drops boost to your wastegate pressure (~0.8-1.2 bar?).
That is just my guessing. Cant tell you anything else without logs. Testing maps without logging capability may be real dangerous for you engine.
PS you have also enabled Launch maps. And you have some messed up numbers in your launch maps...

You should definately make some logging on your new rom.

I drive 1.63 bar peak boost and then 1.4 bar hold with the stock solenoid
That's some aggresive timing you have up top. I'd be more concerned about that than the boost with the knock counts you're getting. What fuel you running?
Its wrong when i think that after i installed tephraV7 for my 96530006 file the old values of the old map goes automaticlly to the tephra file.
Or i have to make some modifications on my Fuel/Ignition or boost maps?
I put the the files on the thread: Wolf Power ist my old MAP and tephra it would be my new MAP (when onetime it works)

The two things that stand out to me are in the Tephra Mod Options. You have valet mode enabled, with an rev limit set to 7903 (don't know if it is causing your particular issue). You also have Drop Boost at High Knock enabled. From your log you're not getting the hitting the 6 count threshold.
First thing I would do is tune the knock out with your timing map. Could you post a log of your previous rom as well for comparison? Do you have a Wideband and/or a loggable map sensor? Those would be helpful to you as well.
It looks to me like you transfered everything you needed to in your maps.

But i think i can tune the knock out also without Wideband, just working with the timing. What do you think?
I have just one with my old map (Wolf Power). With the new map i have to make a new log. Since today my EvoScan works again, so tomarrow i can make a log with the tephra file. At the moment i drive with the old (Wolf-Power) Map
I would drop the timing up top, and not do anymore tuning until you get a wideband. Remember the fuel map values do not correspond to the actual afr you'd see in a wideband. The ecu simply sees the value as an add or subtract fuel as compared to the previous load cell it hit.
When you do get a wideband use this formula to help you dial in your fuel curve.
New Map AFR = (Desired AFR * Map AFR) / Actual AFR
The DAFR and AAFR are as read from a wideband.
