Attention: TDR Forum Junkies 
"I feel we may have awakened a sleeping giant. "
Not quite the same premise, but when I'm done, you'll understand. Hope you packed a lunch, cuz this could be a long one.
Alright, so I'll start with backlog:
My truck was bone stock when I got it and I couldn't keep my power greedy little hands off that. Bear in mind this was 3 years ago, my first vehicle, and the first diesel owned by anyone I knew. I was slightly inexperienced (not that much has changed). Following instruction by TDR members, I cranked the fuel pump. Being as inexperienced as I was there wasn't much of control on the many variables... I just wanted power and a lot of it.
Half a year later, getting that itch again, I went back in a cranked it up some more, with a little more attention to detail this time. I tweaked things around, be it up or down (mainly up) and fine tuned it a little better... kinda. Still rather half***ed by my standards today.
Finally I dumped the money pit... my girlfriend... and started putting money into something that really meant something to me... my truck. I bought BD's biggest injectors and a B. F. AFE air filter.
A few months ago I bought the Master Power turbo on sale at PDR because I spent all my money at the bar and that was the cheapest one I could find. "Supports 300-425 horse power. " And with it I bought a custom cut fuel pin, a Tach, Pyro, and boost gauge. I know... I know, gauges before tweaks... I understand this now... try telling me that 3 years ago though.
So more to the point of this rambling...
I finally went in to put the 366 governor spring in last night. It was a pain, I'll start with that. I got to it without having to tip the pump toward the fender like PB's instructions said. This was out of neccessity, as all the nuts were loose but the pump wouldn't budge (something I'm missing here?). I kept all my previous settings on everything in that pump other than the spring. Put everything back together. Primed it. Fired it up. Idle speed: 1100rpms. Hmm... interesting. Checked all my external parts... springs, throttle levers... etc. Seemed ok. (the idle screw had already been backed all the way from my last "tuning" so I just took it out entirely). I tweaked what I could from the outside of the pump... which isnt much. With it running I realized I could push the throttle lever back with a screw driver and bring the idle down a little... telling me if that spring on the shaft of the throttle were a little stronger, it would bring my idle right back down. I can bend it or something... problem (relatively) solved.
This is where it gets interesting though... .
Took it for a spin. Before the spring, at WOT I was around 32psi, 1200* egt. Now all thats new is the spring. Numbers 42psi at least... thats where I stopped when my egts climbed to 1400+. This was also instant... its like someone lit a fire under the tail of my truck. On the freeway I goosed it and buried the egt needle at 1500*. I can't get on the freeway without hitting 1400 on the onramp before I'm even up to freeway speeds. Boost gauge hits about 42 almost instantly and stays around there until I let off. Smoke... its like a James Bond smoke screen. Don't get me wrong, its smoked real good before... but now at half throttle I can blot out the sun. Its definitely a lot quicker now also. The power gain is almost absurd. Shall we start a pool on how long my transmission lasts... I'll start with 6 days. Any other guesses? $2 buy-in.
Yeah, yeah... it also gave me another 300 rpm top end I guess... I really dont know, as my egts get way too high before it winds out.
My thoughts:
I think all the "tuning" I did to the pump 2 years ago was somewhat limited by the govenor (why, I can't fully explain) and when I put the 366 in it blew the top off pandora's box and let all those tweaks run loose. As I understand it, the governor defuels the pump, and the heavier spring doesn't allow the governor to work until later in the rpm band. This would also mean the governor does even less at low rpms than with the stock spring too... so it makes sense I guess... but the extent to which it took it is absurd... I feel like I may blow something up.
Has anyone has such an experience with the 366 spring? Can anyone give me some intelligent input? Will my truck be alright? How do I fix my egt problem? Will women ever stop spending my money for me?

he is right, loosen the fuel screw.

It's in a bag along with "The pin"!!!!
Where's the link with the pics on how to install the little bugger?
