Those are two of the multipliers I mentioned above. Played with B1181 a bit to see how it moved things, but as far as I've made it yet.

As for the throttle table, I found that the TPS is actually reading APP_D and not APP. APP_D reads 17% when throttle APP is reading zero. So it should never see 0 TPS value according to how I interpenetrate it.

Could you use the appropriate cell to artificially apply throttle where needed to get over the starting hump? I know it is kind of a bandaid but maybe it would still work

Using a value of 100% over in the spreadsheet falls pretty close to my current running tune. Possibly those calculations can be tweaked a little bit based off comparison of the known values at 180MPa if graphed out. I'll add stock LBZ data to this once I get a bit more free time since these are actually LBZ nozzles compared to stock LMM PW numbers.
