Default help me with the boost controler...PLEASE

now i'm using the Profec B spec II Greddy boost controler.. my frind at the mod shop set up for me, but i chcked my last boost was 20. psi.. and i think 20 is too much for my stock turbo..(but its only spike on the 4th gear +
oh.. and i have intake Dp+ cat back - BOv.....
so if anyone have the same set up as my car please let me know what i should put in the Hi and Lo set up to make it safe for my engine...

ditch and sell the BOV & Boost controller, (why are you using a boost controller on a sti with ur stock turbo) Buy a reflash and you'll be happy...

you seriously need to get some engine management (ecutek reflash, utec, accessport, etc). do some more research before making your next modification. buying a blowoff valve and boost control were not things on my list although the TBE was a good idea.

you can run 18-19psi with your current setup but without the proper tuning, why?

if you really want to keep it the way you have it... run 18-18.5 high, 15.5-16 low from there you can tweek the low slight higher if the 20psi spikes stop happening but that sounds hit or miss to me. btw, 93octane or 91 octane?
