Also I am going to be ordering a cam this month, and will be going with a Colt Stage 2 Cam.

I know this is an OLD, or OLDER, thread but I wanted to update some info. It turns out I didn't get 100% of the info from Holset. Not sure where the disconnect was, and they never did call me back with the PR.
But the info below is more accurate.
HE351CW
Compressor Wheel
Inducer: 60mm
Exducer: 86mm
Turbine Wheel
Inducer: 65mm
Exducer: 58mm
Turbine Housing 9cm2
HE351VE
Compressor Wheel
Inducer: 60mm
Exducer: 86mm
Turbine Wheel
Inducer: 70mm
Exducer: 60mm
Both versions of the HE351 are rated at approx 61-65 lb/min.

Hey Gang,
I have not had much time in the past months to post or let's alone say read the forums. Too much stuff all at the same time in the pipeline. Sorry 'bout that. As you can see, even though I'm silent, we're not sitting on our hands.
A few things that I would like to point out about the UDC.
I think the most important news with the UDC is that you not only get a tool but you get also professional help in using the tool to get the tuning right.
AKA, the (stock) parameters that you modify with the tuning software are NOT written into a stock software!
Your modifications are written into my " base software"!
WTH the base SW is? That's the software I use in all my tuning. In other words, the tweaked / performance oriented stock software which is the base for all Smarty tunes. All limiting factors like for example the boost / torque /
limiters ( simple stupid examples there are hundreds of parameters tweaked in the base software ) are already taken care of. You don't have to fiddle with them. I already did the legwork for ya. Example, when the 6.7L first came out, it took me over 2K dyno runs to optimize that "base SW". That's been well worth my time tho The result is that the power can now be taken anywhere by tweaking in the Duration / RP / Timing.
This is where your modifications land in Smarty....
Since it's time to open up my smallish box where I keep my lil secrets in...
I have turned off the late injection event in all my softwares since late 2005 /
early 2006. The late injection event is OFF by default in all my softwares since then. 'Nough said? OK, gotta admit, in a couple SW releases I had forgotten to turn it off. I guess nobody really noticed it.
Oh yeah, I've heard that fantasy a lot of times...turning off the late one gains a fantazillion in mileage. Now you know the (real world) answer to that.
Hint, when you read " Load " , think it as Throttle Position and everything will become ( much ) easier to tune 'n understand.
Cheers,
Marco

Been busy, drove truck for few years, married and divorced, now I'm traveling working out of town back in my cummins again. Driving my freightliner I was a little more concerned with the inner workings of 12.7 Detroit . How's yours been doing?
