safe boost psi level

[mazdaspeedkid]

i just buyed a boost controlller and i was wondering what is the top psi i can run as my hi boost i been hearing about 22 psi can i do the same thing???

I would recommend no more then 17PSI if all you have is a BC. Without a Map Clamp or BCD you will get boost cut at 18PSI+.

i think 17.9 is better than 17 for sure
