Hi Pedro,
If MJMP putted his holy hands inside your MP1, I bet there's no issue there.
Usually, he also fine tunes internal trimpots for correct gain...but, unless you installed a MDRT transformer (in that case, OD1 and OD2 trimpots are set to minimum and there's a lot of gain, trust me....), you can easily identify trimpots and increase the gain on your taste.
Just remember that also noise level will be increased accordingly.
About Nuno's settings on his MP1 (Pornograffiti era, since on III Sides he used a Soldano SLO100 Head and a wah pedal...and that's it, as far as I remember), if you set your ADA that way....most of the times it's a big delusion.
Why?
Well....that's because Michael Wagener used a lot of other stuff with that ADA MP1 in the studio.
Have a look to this video...

I tested those settings many times with my MP1 and the sound it's far away from Nuno's tone until I increase the gain and reshape the eq.
No way.
With those settings, the MP1 is more in the blues territory, as you wrote.
But, if you watch the video I posted above (pause it at 5:04...), you'll find original M.W.'s studio settings for MP1 (patch #45!)...
Have a look to THOSE settings and continue reading...
I watched your video: tons of gain, lots of bass....but...no mids, flat high and low presence.
Use more mids, high and presence and you'll see....you'll have to lower OD1 and OD2 for sure.
Last but not least, on MP1 not only OD1 and OD2 controls influence the overall gain and tone: depending on the eq settings, you could have to tweak the Master Gain and/or the ouput level pot on the front panel to send a strong and rich signal to outputs.
And then the overall tone also depends on power amp and speakers and all the other stuff in between, of course: there are a Quadraverb GT, a BBE362 Maximizer, a Rocktron Intellifex, a Tube Advance TA '70 tube power amp and a 2x12 Blackstar Celestion loaded stereo cabinet between my MP1 and my ears!
See the picture, if you don't trust me...
I've to agree with Richard, anyway: with OD1 and OD2 at 7.0/8.0, the MP1 delivers tons of gain (I use a couple of Ruby selected JJs there, as suggested by MJMP....and wow....).
My tipical rock/hard rock patch is:
OD1 = OD2 = 5.0/5.5
Master Gain = 5.5/6.0
Bass: 9
Mid: 6
Treble: 6
Presence: 12
With those settings and humbuckers pickups, I've a very nice overdriven hard rock tone with enough gain for heavy rhythm, riffing and lead.
Push OD1 and OD2 to 7.0 and set Master Gain to 5.5 and you're in metal territory!
Many people kills MP1's tone with wrong eq settings, imho.
Set eq properly and MP1 will come to life, with a very organic, full, open (=not boxy) and plexi-on-steroids sound.
Factory patch #1 it's a very good starting point to create a good hard rock tone.
Have fun!
PS. those Bugera tubes suck!!!
The best in the video is the TAD 12AX7A-C: put a couple of those in your MP1!
You can also couple the TAD in V2 with this in V1: https://www.banzaimusic.com/Ruby-Tubes-12AX7AC5-HG-PLUS.html
Or put a couple of these in V1 and V2:
