I'm sure someone else will chime in, but it has to do w/ the PCM registering that the front wheels aren't moving when they're supposed to be.....

transfer case is a "viscous diff" i believe, regardless, take the front shaft out and the rear wont move, power will transfer to the front yoke only since it has the least resistance. something like that. you can bolt a regular trailblazer new process transfer case in and leave it in 2wd. if you want to go through the trouble.

Actually that isn't a problem when you pull a couple fuses. The issue is that we have a mechanical transfer case and it will hurt the Torsen unit by pulling the front shaft. It cannot be electronically disabled like some other AWD systems. Find an AWD capable dyno.

from my understanding a dyno is just a measuring tool for tuning, not a true judge of power. for example you dyno at 300hp, then adjust some tuning and get 320hp it shows you that you tuning is working or not. the actual number doesn't mean a whole lot.

Is this correct?

Yes that is correct. Some dynos read different then others. The drag strip is a true measure of actual performance. A dyno is just a tool that allows you to fine tune some aspects of the tune without having to top out third gear on the street as well as hit some cells in certain tables that are hard to hit on the street (depending on dyno type).

Yes you can run a AWD on a 2wd dyno. Its been done. Pharmd did it with his, tuning was done by Blue Cat in eastern KY. And he knows his shit. They used a standard 4wd transfer case in place of ours.

Yep. If that is less trouble then finding an AWD dyno and even then it doesnt simulate street load.
