Wanna say hi to community and I have a question in mind.First off, let me post my set and then get into my Q's.

92 KA24det-t3/to4e standard turbo, 50 trim,63a/r-Stock motor meaning stock FPR, injectors, and ecu ofcourse.

Right now I'm running 5psi because I dont wanna risk blowing my motor. After a while driving, 5psi isnt satisfy me so I wanna increase my boost to 9-10psi but right here I need some help. I wanted to get 370cc + SAFC but I'm not familar with how to tune it. From what I see from my friend safc is it has a RPM chart and this you can control how much going into the engine. If I use 370cc and decrease 27% at the low rpm so it wont mess up the idle and increase 27% around 3500rpm to match with the injectors duty, will it work if I do it like that? Also will the stock MAFS handle 9-10psi? And do I have to play with the timing and FPR? I'm pretty new to tuning turbo car so any suggestions I would greatly appreciate. thanks for reading.

i went thru the exact same problem as you did 2 weeks ago. i didn't know how to tune the hi throttle setting. i know you might not want to hear this but i'm gonna say it to you as well. you need to have the car dyno tuned. i cannot give you my settings because every car is different. in fact i can give it to you but you might not want to take it becasue the settings are quit scary. the only reason why i'm using it is becuase its been professionally tuned with a wideband O2 sensor. and its still running conservatively rich.

Hi throttle

1000-02000=-303000=-354000=-355000=-395500=-356000=-366500=-36

Lo throttle

1000=-282000=-283000=-284000=-285000=-225500=-106000=-76500=-0

throttle point

low =30%hi = 65%

as you can see, your leaning the **** out of the car on the high throttle. now how are you suppose to know when is it too much? you really need to get it dyno tuned. i didn't want to believe it until i saw the settings done. then i was like how da hell am i suppose know it was goin to be leaned out that much?
