More details of your mods would be helpful.
Otherwise, it sounds as if you may have a failing injector or coil pack on the left bank (bank 1). You can use the scan tool to monitor the fuel trim, then I would systematically swap coil packs and injectors from bank to bank to see if the problem follows.
