10psi t25 question

[rotation3x]

whats up i just put my other t25 on my s13 black top on last night since my other one blew which was running 7 psi... guess it was old anyways i put the other one on and its running 10-11psi i have a walboro fuel pump and and vspl fmic. I was thinking it was only suppose to run 7psi i dont have a boost controller far as i know my intercooler piping is all tight i havnt checked the wastegate its not dented or any thing .. possibly sticking though. I read a forum about running the vacume hose to the TB then to solonoid then to waste gate i dont know you will get 10-11psi that way but i got mine goin from tb to wastgate to bov the t is at the wastegate and bov. it was also a light back fire at idle kinda like a little poof poof sound. i have brand new ngk plugs they are gapped at like .32-.34 i think thats to much they are the ngk br7es i think copper plugs

but if anyone knows why it would be running at 10-11psi and what the gap on the plugs should be that would be awsome. thanks to any help
