I figured out why the timing map seemed like it wasn't responding: I was logging the wrong PID. I was logging GM.DYNCYLAIR and I was supposed to be logging GM.DYNCYLAIR_DMA which is the speed density version and the 2 are calculated very differently. WIth the correct PID I'm blowing the lid off of the stock map by quite a bit and my boost timing puller dealy isn't configured correctly so it's not doing anything. Whoops. I'm about to flash a new MAF calibration in and hopefully figure out why I'm getting these wonky correction values for my VE to get it cleaned up so I can go back and add in some timing where it wants it. I think I've pulled a little too much at the moment as the truck is only getting single digit timing advance at WOT. I'm going to re-enable the stock PE timing adder so it only adds the timing when it's dumping the fuel, but it hasn't been adding enough fuel down here hence me going after the VE/MAF stuff.
