Will the new stuff address the duration drop also?
It has a little but mainly fixed the dropping mm3.

Kind of sucks that I busted up my bed and lost a tail light, but I might still try some testing soon too since I'm out in the country. Hopefully this will get me a little more power. Really need to take it to the track already to compare times with the Smarty.
Is 3500 RPM the limit on a totally stock motor? That's what I've gathered from reading so far, and then you need springs for 4k, possibly a cam to get the extra power up top... I want to get springs, cam, studs, and maybe a little head work done on it one day, but don't know what 4200 RPMs would do with stock fuel system and turbo.

What turbo are you running?
3500 RPM's is "okay" under stock boost conditions, but really you won't see squat with that stock cam anyways. It's pretty pathetic above 2800 RPM's.
A stock Cummins is rated at 4200 RPM's for a 15 seconds in an over speed condition from the factory, but that's assuming valve springs that aren't already tired.
If you're running anything more than a 62mm charger or more than 45 psi of boost, you won't want to run past 3500 without heavier springs or you'll be floating some valves.
Like I said though, with a stock cam, you're kinda wasting your time anyways.
Stock turbo. Thanks for the info. I've been wanting a cam, but want to wait until I can do springs, studs, and maybe some head work all at once and then be ready for more fuel and boost.

I normally tell guys to do the springs, studs and injectors at the same time. Otherwise you're just repeating labor.
With a cam....you want to do that ALL BY ITSELF.
It you start doing a cam, sticks, turbos, etc., all the same time, it makes it a PITA to weed out issues.
The only other thing I like to swap when we do cams are the pushrods, just because they need to come out anyways.
I was thinking injectors and turbo later.. just some head work, springs, studs, and cam for now.. where you recommend starting and how much at a time? I plan on waiting with injectors until they go out, and turbo whenever I decide to I guess.

If they go out your engine could possibly go with them if the nozzles go aswell.
