Hi. Just over the past couple of days I have been experiencing this issue with N1 where I over speed while on TOGA on take off
Has anyone any idea. Been flying this beauty since release on Xbox without issues.
Not on BeTa
my solution and don’t put the maximum of the levers if it continues giving error I recommend that you reinstall or ask for help with pmdg itself

Uninstall and install was my next step. Contacting PMDG will only result in them complaining in their usual condescending way

Here is a short video of the problem
I uninstalled and then installed and this is the result
It looks normal to me, apart from the fact that you have to stay in the center of the runway, not on the right as if driving a car 
You obviously didn’t watch all the video.
It looks like you’ve not correctly set trim, or are not rotating until multiple seconds have passed since rotate speed. You then only pitch up to 10 degrees nose up, so of course your speed will trend upwards still. We can’t see the upper EICAS display in your video, so it’s very difficult to help further diagnose the issue.

Ok thanks Chewy. That’s interesting that as I have done multiple flights and the same happens
I think the video because I wasn’t set up correctly was an injustice so let me try again
Thanks for your input as well
@Chewwy94 does this make any sense. You will see the aircraft is configured IMO correctly and after rotate the plane veers to the right. This video is the latest
It still doesn’t help much because we can’t see the upper EICAS. Can you record not in vertical so we can see more of the flight deck? It would also be useful not to have the yoke lowered to see what flight control inputs you put in. The aircraft will veer off to the right like that when you have a crosswind and haven’t corrected for it with your flight control movements.

Unfortunately the videos don’t help for your problem. It‘s important to see the engines display during all your takeoff procedures.
But normally the engines wouldn‘t spool that far up, something is off. How do you control your plane? Yoke/joystick? Throttle quadrant? It‘s impossible to help without any information, all we know is the PFD although I can‘t read anything in the videos, might by my smartphone though. And that it veers to the right. Could it be that I read a 40 knots wind on the ND? That would explain the veering thanks to MSFS‘ bad ground friction. But the engines could be caused by hardware firewalling your throttles. Depending on the settings in the CDU options you can override the software throttles always, in „hold“ mode or never.

So lined up same runway EGNT RW25
I have put three images below. One in a state of ready to roll.
The second is during roll prior to take off and the last is immediately on V1
This happened all day and all weekend. Once I have gear up and press autopilot at over 1000 I seem to get back to N1 level as expected.
Are these showing you what you need to give me advice
Did you input the gross weight correctly in the FMC and set the trim wheel to match the value given?
I noticed the engine tone change when you pulled back the yoke to rotate the aircraft. Have you checked that there are no conflicting control assignments?
Have you checked that each of your peripherals aren’t generating noise which may confuse the sim?
In the MSFS assistance settings page, under piloting, have you turned off all options?
Are you using control profiles with the external programs Spad.next, FSUIPC, or Axis and OHS?
You may need to try a flight with all other mods removed from your MSFS Community folder and any tweaks you performed on any base sim files.

Ok just to give you heads up
Turtle beach V1 yoke
TB pedals
TB headset
TB stand
Xbox X
26inch curved monitor
Unless something has changed my settings am unsure as to why it/or they would have changed.
I set gross weight and trim wheel to 4.74
Which engine derate settings have you entered into the FMC? For me it seems like you have selected the 27k bump. Try a 22k or 24k derate. And take a look into the post of Chewwy94.

Per you screenshots, the FMC calculated trim of 5.04.
While it’s not massively different, it certainly won’t help your rotation to have set trim to less than what was given.
Please take a landscape video of your take-off, ensuring the upper EICAS is in the shot, and put the yoke in the up position, as Chewwy requested.

I am so sorry but I now for some bizarre reason know what is happening.
Why and how only Microsoft can explain as to who and why changed take off assistance as it was checked.
I have flown over 1200 hours in the wonderful PMDG 737-800 and why and how this changes is beyond me

Software gremlins, unfortunately.
Good to hear you found the cause of your problems.
Happy trouble-free flight simming!
(You should probably mark your reply above as the solution. Saves further troubleshooting attempts by others who may not have read it).

Thank you ever so much and for taking the trouble to answer
It is frustrating that this happens. At times I feel like giving up. But I appreciate all that contributed to the query and I wish you all well
