Diezel mod:
C35 : remove
C34 .047uF
C25 : remove
these three mods remove harsh
C42 1uf
D3 DEL
D4 1n4001
------ make the sound more dynamic and full
C36 .1uf----- EQ more usefull
Boogie/Bogner mod:
C35 a enlever
C34 .047uF
C36 1uF
D3 led
D4 1n4001
EN PLUS:
R46 increase values, more pre-distortion + mids
R41 reduce value you obtain more distortion (470ohms to start)
Mods don't have the same sound of diezel amp or Bogner amp, but it can be better tant the stock sound.
Keeley mod:
C20 .22uf
c42 .1uf
c37 , c39 , c17 , c11 1uf
c8 .22uf
c9 .1uf
c20 .22uf
d3 , d4 LED

...i can't seem to find any info on the capacitor that replaces D3, from the pedal gut shot pic i was able to read the last two digits "21" but i can't make out what the first digit is? Does anyone have any info, or can someone make an educated guess?
...
'm guessing that's a 220 pf cap on D3, correct?

Dfer, your guess is correct: that photo does show a 220pF capacitor in place of D3. The digits are 221. (I suggest downloading the full-size photo from the website where you found it. You can zoom in fairly close without it getting too blurry; I was able to read all of the visible component captions in this way)
There also appears to be an additional (non-light-emitting) diode underneath that heat-shrink tubing on the right hole of the D4 spot. Based on my experience with his DS-1 "Ultra Mod" and a quick look at my MT-2, it seems, from a quick glance, that this part of the mod is similar to his DS-1, in that flipping the switch to "Triple Diode" mode places the second LED in series with this diode, and switching away from it removes it from the circuit. To my ears, this part of the "Ultra Mod" alters the sound by increasing bass response, adding some "saturation" to the overdrive sound, and giving the pedal a bit more dynamic range (or "pick sensitivity"). This is just my assumption, however; don't take it as the gospel truth, as I've never seen the inside of one of Mr. Keeley's pedals aside from the photo in your link, which, unfortunately, doesn't show his mysterious 3-way switching wiring.
I'm not sure on where you stand with respect to reading capacitor codes, but just in case you (or anybody else) might find it useful, this site contains a free online tool that calculates capacitance from the numeric code on the case (and vice-versa):
