The logic is IAT based, suppress IAT and you can keep the boost down. If and when I run the Cobb stage 2, I'm considering running a DO1 nozzle strictly for charge temp cooling on a 50/50 mix; I bet a gallon will last me months! That'll keep boost at a reasonable level
Btw, no discussion needed about load targeting Vs PID. That's been beaten to death already. The possible cylinder-to-cylinder ignition variance, well, thats a new topic
