The issue: when changing displacement in the CMR software, you'll end up with an ESP/BAS light permanently on. Also, your ESP disable button (squiggly lines) will not work. Traction control seems to be somewhat disabled, but you don't have control over how much, or when.
Diablo's default answer has been to not change displacement in the tune, since (1) adjusting for the proper displacement doesn't fix anything in the tune and (2) leaving the displacement as stock will avoid the ESP/BAS light and traction control issues. I believe most tuners are not messing with displacement as per Diablo's recommendation.
However and contrary to Diablo's statements, my testing showed that the car is just a different animal when properly adjusted for its actual displacement. Traction/light issues aside, it just *feels* different. No, I don't have any hard evidence of this and yes SOTP dynos suck... but I'd swear adjusting for the proper displacement woke her up even more than she already was. Perhaps one day I'll get some dyno/track time and we'll see...
Something we can confirm though is that your VE tables all the sudden start to make sense when the displacement is properly adjusted. No longer do you have to scale your values off into outer space. This will make your tuner's day.
Our very own Lafrad, buried in another thread, shared a gem of a fix that he discovered after a weekend of effort. I tried his fix last night and can confirm the issues are gone; the ESP/BAS light is now off and I have my ESP (squiggly line) button working again. Traction control now is in full effect when I want it, and I can turn it off (via the button and GSM mod) when I dont.
Here it is:

Great stuff Mike and CV! I agree 100% with you CV. Bob@SVS gave me a tune with the displacement correctly changed to 6.1 to match my new engine, and that tune felt SO much better on both street and strip.
And right in the middle of typing this, Bob emailed me to fix it - gotta love that kind of service!!
I can be even nicer here:
The same cam has a *VERY* similar shaped VE table in a stroker vs a non-stroker.
5.7 vs 6.1 vs 6.4 vs 7.0
its startling how the tables are almost plug and play from one to the other.

About the airflow tables... its jsut for the '05's.
I only have... oh... wait... there's a few of them ;-)
I *DID* find the '04 SRT4 injector scale from mopar tho, so yer off the hook on that one :-)
