calvin,
derek issue is having siemens ecu. i must admit i got no knowledge about siemens ecu but i do know its very "hesistate" to the mod. Even u put in the piggyback, it will reset back into stock setting. same with kelisa and kenari ecu problem. so unless he get the ecu sort out, else i dun think even he do mechanical mod will benefit him. afterall u will still need to tune ur AFR.
your white smoke must see how is the colour and smell. FYI, if piston ring gone, valve seal gone or any leak, normally u wun see the oil will dramatically loss. u need around 1-2 months time thn only will tell
