[chinaone]

Hi i am running 10.5psi at mo, with FMIC, Air filter, decat, hks hi power system, hks atuator, sometimes when i put my feet down i get fuel cut? why? i am stillll under 12 psi, so??????????????
I have a JAM FCC waiting to go on, but i haven't get any fueling mods at mo, so i haven't put the FCC in yet, but is it ok to put is on with no other fueling mods?
thinking of Safc. or do i need a fpr?

Ok, will try change the plugs, see what happens. But i would think so, When it cuts SOMETIMES not all times, the engine lights comes on, but after a few sec it goes. whats that mean than???
