Yes.
In the map properties, for the MAF map, goto the Cell tab and constrain the cell size.
When viewing the maps, click the x-bar button to view the MAF map correction factors and the VE map calculated VE values.
In the tunetool, go Edut->Properties and set VE units to g*K/kPa.

I'm still looking at your tune file...

I feel like there has to be something in the tune that is just too far out of the parameters of the engine dynamics that needs to be improved/changed before I can really get the Calc.VET procedure to produce better results.
Have you guys ever started from scratch basically with a tune where the car just didn't seem to run right and went straight to Calc.VET? It just seems like I'm missing a critical point somewhere that needs repair before the tuning should really start. The engine ran fine with the original 165 tpi ecm, so I'm quite certain that the issue is not mechanical and I just replaced the headers (and gaskets) to be certain that I wasn't getting fresh air contamination on my O2 sensor readings.
I know that the car is running lean at normal cruise (the exhaust gas is so hot that it is discoloring the ceramic coating on my brand new headers) but it's choking on fuel with any semi aggressive throttle... I'm pulling my hair out here because I know what's going on, I just don't know how to solve it!
Try this:
set B0120 to zero (or any value below 200 rpm), this will force MAF only;
then bump up the MAF table where fueling is lean... you could use the MAF map, but be sure to apply the throttle transient filter.
sometimes it helps to start again from a stock tune.

BTW:
table C3003: set the out-of-range cells to in-range values as follows (there's a trick to it):
set the blue-eared cells to max-5, save file, exit tunetool (all the way out), reopen tunetool, set those cells to max value, save file.
Doing a calculation to sanity check your IFR table:
your 0 kPa cell is 4.0547 g/s --> this is 32.18 lb/hr so this checks ok.
your rail pressure is 44 psi (asm mentioned above) --> this is 303 kPa
your 80 kPa cell is 4.5547 g/s --> calculation says it should be 4.0547 * sqrt(383/303) = 4.5586 g/s, this checks ok.
And, your FPR is un-referenced, so your B4001 IFR should be sloped (slope goes as sqrt((300+VAC)/300)), as it does.

Do you have data for table B3701...?
Do you have table B9021 (defined by cax file) for Minimum Transient Pulsewidth...?
( if you have the data, see post #12 here: 17699-need-B9021-for-01250003 )
