little worried...

So iv had my turbo integra for a little bit now… a month and a bit…and iv tried to find some answers but i cant so ill just ask it

Fuel i usually run is 91 is this to low?, and should go up to 94? i dont hear detination or any missing under boost

I have a b18a1 stock everything 6psi on Stock injectors
t25 turbo
intercooler is 42 inches long 7 inches tall and 3 inches deep so i know i get really good cool temps going into my engine… i know it’s not safe and all that no so fun stuff, but im stuck wit money, and i dont beat the crap out of it everyday.
