I set the values to 0 and am happy. I get proper A/F while going partial throttle/boost now! Before it would just be lean for to long before it switched to the Open Loop Map.
I do go a tad lean if i'm ever so slightly on the throttle (10% tps) but I've made adjustments to the tip in enrichment (added 20%), so I'll see how it helps out!
Regardless, zeroing out the delays gave me the control I needed in the Primary Open Loop Fuelling map.
