Sup, I was wondering how much i can turn my boost up with my current mods BEFORE I experience FUEL CUT
 
right before your engine blows into pieces. you should not turn up the boost without some sort of EMS.
 
I'm at stock boost with whatever mods are in my sig and I hit fuel cut if its like 60 degrees or colder outside. It sucks ass.
 
EMS is Engine Management System.

They can range from 300 to 1200. If I were you I would do research on the DSM AFC V2. Do a search for AFC.
 
Alright good, thanks for the info. Now, another question..what plugs should i use and should i go a step colder? I'm spiking about 12 psi and settling about 10 psi
 
If I were you, I would turn the boost down a bit. At least until you get an AFC or an EMS. Trust me, having a slightly slower car is better than having no car. I'm about to got forged in a few days. But I know on the stock fuel set up, even with forged internals, I could only do 10psi safely. Just some food for thought.
