did the same settings as theswapshop. light throttle is cool, anything more than that it bogs out. my fuel pressure is set at 38 psi. when i rev it, it drops to like 30 psi. runnin the hack, dsm 450's, and walbro 255l pump. then i checked my plugs, and that **** is hella black ! i dont understand, i justed finished replacing my hg, and it ran fine before.

 

sensors 6 in, 6 out right ??

You are running too rich, if you know what your doing slightly adjust the afc or get on a dyno.

 

No, fuel pressure shouldn't drop like that.
