My 4.2 is set to enable at 1700 and the enable MAP is set to 25. I have compared a couple other tunes that show enable at 2700 and MAP at 20. Does this help with fuel economy or what? I am having a hard time understanding this.

Well when WB tuning you should take off DFCO as it's one less additive. As for economy your 1700 RPM enable would be better for fuel economy, but lower map # would also. I wouldn't expect a huge gain. Maybe if your lucky close to 1 MPG.
You raise, not lower the MAP enable & disable tables. This enables the DFCO at a higher MAP for easier fuel cut.
