Hey guys, so i started running really rich out of nowhere. i pulled the plugs and all black. so then i pulled the rail and did the leak test. cyl 1-3 sprayed fuel(not o-ring leak). i did it again and then only 1-2. i figured my injectors were bad so i bought replacements. install them and still running rich. i pulled the rail again and did the leak test and the same injectors sprayed fuel out momentarily as soon as the key was switched to on(i did not crank). so the same injectors are spraying. ecu issue? tune? i have a mine's ecu with a different daughterboard tune. the mine's ecu didnt come with a diagnostic LED either(i know, it makes things much more fun)

so my daughter board with my tune came disconnected, but now the motor is still running rich after plugging back on the board. when i pulled the rail for more leaky injectors, it passed. none of them leaked or quirted.
