I'm not an expert but from what I've read, this is what you need to do.
turn off the pilot injection.
Change the cam to one designed for mileage.
The stock cam is too short on exhaust duration for EGR purposes.

Then install 50hp injectors and advance the timing.

If your Smarty is up to date your 3rd injection has been disabled. The setting you are running should get you the best mileage.
Make sure air filter is clean and fuel filter is new or at least not in need of a change. Not sure of the tire size you are running but make sure they are properly inflated.

That is the same size as mine so tires wont be hurting your MPG. Plug in your Smarty and quickly see what version you have and post up here. Chances are it is in need of an update but also very possible that you have a new enough version that it has the 3rd injection turned off.No. The 3rd injection event is for emissions on the 04.5 to 07 engines.
Marco posted up on another forum that he has the Smarty turning off the 3rd injection for a while now.

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

Wow,so my Smarty Sr. has the update released for us Cali guys who had the dealer do the KO1 emissions reflash. If I'm understanding it,I've got the 3rd injection event cancelled with this update? I don't use the default settings. I just use sw#3,stock torque management,#2 timing,stock rp and wastegate settings.
My oil still turns black in no time.
