i have a 94 civic dx turbo and i heard white on spark plug means youre leaning out right? if its true then i'm leaning out. i have a a/f gauge and it normally doesnt show lean even when under full boost but the gauge probably isnt that accurate right? anyways i already have a inline fuel pump and what else can i do to help with this problem? if it helps i have a greddy sohc turbo kit minus the blue box. i'm running check valves and a FMU.

 

your lean get some bigger injectors, do the vafc hack
