Default vafc and 3 bar map 14psi

I've got a 99' si boosting 10psi with the vafc,walboro 255, and dsm 450s, adj fpr. I wanted to turn up the boost to 14psi. This is with a .60 t3. Right now I'm making 246hp, so I wanted 280-290hp. I've heard that with the vafc the max amount of boost I could run is 12psi. I wanted to know if I can run 14psi w/vafc and a 3 bar map? I know people here frown on the vafc but it's what I got and is easy to tune. Although I'm going to take it to a dyno and the guy who tunned it before will most likely be tunning it. Let me know I want to make more power.

i would think that you may have to get a chipped ecu setup for a 3 bar then use afc but if your gunna do that might as well just get tuned on Crome/Ectune

If you convert to OBDI and use a chipped ECU, throw the AFC in the trash.

Since you obviously already dont want to listen to what anyone is already going to tell you here...just take it to your tuner and let him do it, he must know.

I just wanted to know if it was posible to run a 3 bar map with the vafc so I can run 14psi. Guess it's not possible from the replies I got.

Ask your tuner, if he doesn't know if it's possible, how the ---- is he gonna tune it
Just buy a chipped P28 and 3 bar map sensor.
