foreman told me that those 272/275 camshaft will cause rougher idling and performance gain not much with my 4G13P VDO. He said piggyback would be better choice for me. Any opinion?

slightly lumpy idling... u get better pull at higher rpm....
piggyback ecu is useful and gain alot when u have hardwares installed...
stock standard engine not necessary need piggyback ecu laa....
