Well after searching and discussing this with another buddy of mines, where does every one set their gap at and what plugs do you guys run? I usually use the bkr7e-11's from Ngk with stock gap, Everything seems to be ok for about 5psi of boost on a b20Vtec with a gsr head. The only thing is that im using Skyline injectors now that is 440cc and plus im running it with the fuel turned down almost all the way on a vafc with 43psi of fuel, This is fouling out the plugs, so the next thing to do is take off the FMU and see what happens with a brand new set of the same plugs, any suggestions? Should i keep the plugs at the stock heat range which is 6 for better burning of the fuel or should i stay with the 7's and do a closer gap? Thanks guys!

Your spark plugs aren't the problem. You need to Ditch the AFC/FMU and get some good fuel management.
