Hi gents Need some assistance. Ive got a built bottom end 5e ,550cc injectors with a gt30 managed by E-Manage ultimate. Ive been gettin this fuel cut lately. No check engine light no knock. car drives fine but occasional i get some sort of fuel cut at around 4k rpm for 10 sec and the the power comes back on. Sometime i wont be on boost at all an i get this fuel cut. AFR are ok. the car doesn't break up. just this random fuel cut. Changed fuel pump changed FPR Changed king lead Changed fuel filter The emanage shows voltage from the map sensor. any ideas what could be possibly wrong? thanks.
