It really depends on what coils you are running. if you are running the LS1 type coils, I recommended running B10EGV. If you are running DSM type coil, stock BUR9EQ will work fine.

So run B10EGV on the leading and BUR9EQ on trailing for 12 psi

^ no, he means 9's on both leading/trailing if you are using Mazda coils or 10's on both leading/trailing if you are using LS1 coils. Moreover, when using diferrent heat ranges the easiest way to remember is "L"=Lower Leading and Lower number heat number spark plug. Since you are using Bosch (not oem) then most likely he would prefer you use six 10's.

If you were get 9/10's then 9=L.
