this has probably been covered before but i cant find anything covering my specific issues..
have a 32 normal mods fmic, turbo back 3inch exhaust, elec boost controller (gizmo ebc), 25 neo turbo running 13psi
the other nite went for a drive boosted fine.
the next day it wasnt hitting 13 psi but would still come on boost good and hold say 11-12 psi then when u set a higher setting on the boost controller it would hold a higher boost. so when set to 13psi sometimes it would hit that boost and now sometimes it would only hit say 10-11psi.
then today when i went to hit boost after warming it up it spluttered and missed then backfired with a cloud of black smoke (so would be fuel) then after that was boosing again???
some help would be greatly appreciated!!
my ideas are...
-ebc
-actuator
-fuel pump
