Here is a bit different spin. It's the direction I would have taken to set things up.

Undriveable... but I don't blame you... my setup is barely driveable... I will change that throttle body... i am tired of dealing with it.
SS.... just so you get an idea... I kept fiddling with this.... the problem lied in the OS...I changed the OS and everything went fine. I ran the COS5 and had NO issues. That was my previous setup. I wanted to go back to a regular OS. I enabled the MAF on the custom OS. Maybe I have a problem with the maf, which honestly didn't bother for WOT fueling. I do feel the car was a lot more responsive with the MAF on than TPS/VE and SD.
Hmmm...I'd be curious to try and play with this one-off. But, that's not going to happen. Best of luck! :)
Thank you SS, this tune is DONE.
Curious when I change to the corresponding OS with the same calibration (both are maf enabled) the idle gets all screwy.
