I agree.
So I should see the pin push out at max throttle - if not it's still sticking too much...

I had a problem shiming the governor, I lost a c-clip. I was able to test to see if the pin on the LDA works, and it does now with little effort by the throttle lever. Only I noticed if the lever isn't set properly - high enough it won't come out. I've been up to now setting the actual lever that connects to the throttle cable, more or less by fueling; meaning I'd set the fueling an couple turns down from full and install the throttle lever where it idles properly. I need to review this and see if that's the correct way to do it as I didn't mark it when I first took it off the pump.

I didn't change anything with the fuel system. I followed a few posts on here about the throttle lever and started it, once the top was back on, about half way so that near full throttle the lever would force the little pin out into the lda pin area (left the lda top off till the end). Put everything back together. screwed the fuel pin in about where I figured and then set the idle...and majic...the car pulls hard now and will shoot past 20 psi easily - just a bit too much smoke now. That's easy to adjust down and adjust the lda to where it's just starting to get gray. I love it, the Mtdi is so much easier. A bit of patience setting everything, now it's a fast car. Much faster than my 1.6td.
Fantastic. Thanks for all the help!

Nice work Rod. MTDI's are definitely more of a challenge to get right but once you get there, hold on!

I have one more question-it's pretty darn fast now. I know vanbcguy is running a different, modded cam. I'm wondering if it would make a difference to help mid-range even more (2500-3500 rpm). I don't go over 3500 rpm often. Just curious if it's worth it? Thanks again for the help!

The "Stage 2" cam would be a pretty good match for your turbo/injectors.
Here's a few dyno graphs I found on that "other" site:
http://forums.tdiclub.com/showpost.php?p=2915670&postcount=1Small HP gain in terms of peak numbers, but significant gains in the 2K+ RPM range till it hits peak, and more area under the torque curve...
This one is a "Passenger Performance" cam, Passenger doesn't do VW diesel stuff anymore but a little birdie told me that this is really a Colt Stage 2 cam more or less. Makes sense as both Colt and Passenger are close by each other out in the valley here.
http://forums.tdiclub.com/showthread.php?t=162024Again small visible gains but higher peaks.
Universally though you see lower EGTs, which in turn means you can crank the fuel up a bit more, which itself will gain more HP. So yeah, you'll definitely see some gains.

At the moment if I floor it to see my highest egt, I can get up to about 1300°F at roughly 20-23lbs boost. It's hard to watch everything because before you know it your doing 80 mph.
Where'd do purchase yours? Kerma in US? Do you need to send your old to have it re-done?
I think I will look into getting one sometime soon. If it's going to help EGT ans smoke some, it only makes sense.

Colt Cams is actually local to me here in BC, so I just drove out and bought my cam directly from Geoff. Nice guy, we chatted a bunch.
Kerma has an exclusive distribution contract in the US and I think the UK. I bought a brand new cam, not a regrind (not sure which product Kerma is selling) so there was no core to return.

My buddy picked up a couple directly from Geoff as well. He got the stage 3 and I got the stage 2. I had to do a little bit of grinding of the lifter bores [some heads don't need any grinding] to clear the stage 3 but the stage 2 is a straight drop in. At the time Geoff was working on a stage 4 cam for the ALH. Roughly the same as the stage 3 but with more duration and lift on the exhaust.
I would recommend a Colt cam to anyone but only after doing other mods like bigger nozzles, larger turbo, larger exhaust and cranking up the fueling. A three angle valve job and porting go very nicely with an upgraded cam.
