ka-t tuning help

[apex128]

Hi guys,

I am trying to tune my ka-t on nistune and am a little unsure about the timing map. So far, I have tried to pull 3/4 of a degree per psi of boost. Basically I need to know how much timing should i pull per psi to have it be safe but still make power? and what load scale equals what amount of boost? I was looking at other people's ka-t timing maps and they seem to have much more timing pulled throughout the whole map, even in vacuum. My setup is an s14 ka, automatic ecu, t28 turbo, and 370cc injectors.

Thanks
