Respect for your work bro
It should be in /Sdcard. did you check there?
I begin the works on the new and think last version of Tiramisu based on CNA...
I wipe Cache, Davik Cache, Data/Factory Reset, sdcard and /system with CWM before i flash
Did you real FORMAT System ? because wihout all work fine but in slow motion like you discribe. Wipe Data, wipe Cache, wipe Dalvik Cache, FORMAT System, Format SD Card, mount SD Card to PC to copy the ROM, install the rom.
The performance within and without Format System was enormous on my phone (1200 to 3200 Benchmark points)
