Doing the math on that map shows that the PCM-commanded injector pulse width exceeded the IDM's capability severely under high load/RPM situations. This thing would fart and pop terribly with any decent amount accelerator input at high RPM.
8 ms is very excessive, even with low injection pressures. However, unless something is wrong with the truck, you won't be at 100 MFD and 435 PSI of HPO. Interestingly, the IDM is capable of supplying up to 19.22 ms at 750 RPM. You certainly couldn't run that much and have a driveable truck though. Conversely, the IDM is capable of running only 3.7 ms at 3350 RPM without having issues. Another thing to keep in mind is that unless you have your MFD vs. Boost map allowing 100 anywhere, you really won't get 100 MFD commanded anyway and that last tune I showed you has 100 across the board.

Wow, I'm so lost as to what was being asked, and how Dave came to the answer... I thought I had a grasp on this stuff, but it seems I don't have a clue...
How did you guys begin to grasp all of this?

I'm going to start charging for this service.
Not really. I'm actually trying to make screenshot movies made right now. I got a program that seems to work pretty well so I will hopefully have some decent instructional videos up here shortly. Be patient.

I have an adobe program that will do instructional computer video type movies .. umm Its Adobe Captivate.... I think there is a trial on their website....
the thing that makes it so confusing is that so many maps and variables are interdependent on each others. you can't just set one variable and known you will get that as a result

Any more Minotaur quiz's?
I actually found the last one quite useful today, had a little too much fuel in a certain situation and was able to pinpoint the exact spot in the PW map that needed tweeking.  I know you are pretty busy right about know, but I got a kick out of the last one.  Now only if there was an easier way to know exactly what the APP A/D counts are while driving.

204 A/D counts per volt. If you have a scanner and can see TPS voltage (which you should with any "good" scanner), it's pretty easy. Just a bit of math.
Say your scanner says 3.67V for APP. Multiply that by 204 and you get 748 A/D counts.
